If this is the wrong place to ask, please do move it and accept my sincere apologies.
So I've read Google Maps will start charging $4 for every 1000 clicks over a threshold of 25,000 in a 24 hour period.
I'm not sure too sure about how this will work. What defines a 'click'. A maps API call?
I have a website. A large website in terms of code and functionality but a small website in terms of use. It's a new website.
On a users profile, there is a map of their city.
If they go to a location to look for bars, clubs etc. There is a map with pins of all the venues in that city. In search results, next to the result, I also show a small map of where the venue is. If I show 25 results, then I'll have 25 smalls maps. If I go to a venue page, there'll be a map also.
As you can see, I use the maps quite extensively (I really love google maps!)
There are quite a lot of calls to the API, but I'm not a big company. Far from it. I'm just a developer trying to launch a site and hopefully it'll be successful. So if I start getting over 25,000 in a 24hour period, the cost of running the site will go up exponentially. This is easily achievable. I wouldn't need many users to achieve this threshold.
If I got a 35,000 'clicks' per day. That'll be $40 per day and about $1200 (30days) per month. I couldn't afford that.
I would only need 100 users loading search results 10 times to achieve the 25000 threshold.
So, can someone please clarify what counts as a click. If I reload a page which has a map on it three times, does this count as three 'clicks'?
And from a programming perspective, if indeed this is the case, is there anything I can do to reduce API calls? in terms of caching etc.
BTW, I'm not using any address looks up. I'm using latitude and longitude for everything.
Thank you in advance.
EDIT: I'm not against Google Maps charging. I know they've put in a lot of money into it. However, $4 per 1000 clicks would be effectively bankrupt me.
The FAQ
http://code.google.com/apis/maps/faq.html#tos_mapload
has this information.
basically every time the browser calls the API loading tag
<script type="text/javascript" src="http://maps.googleapis.com/maps/api/js?sensor=set_to_true_or_false">
Trace how many times you load that. Google have Analytics that could be used :)
(You could perhaps convert all/some 'small maps' to Static maps. you get 25k of them as well as 25k dynamic maps)

I am trying to make public transport time schedule app using google maps directions api.
Whats the best way to get all of the possible departure_time's for a specific route from one place to another from a specific time?
The problem is, the server is always responding with only one route for one specific time. How can I get all of the following departure_times?
The worst way to do this is asking server every minute if there is some new travel link. But hey, its gonna take a lot of time!
So I thought google might be providing some kind of transport schedules but I can't find any info on google developers webs. I saw only the way to give google schedule information with the help of General Transit Feed Specification (GTFS) here or here.
But I can't find the way to get it from them.
I don't believe google maps directions api will return the information you are looking for as a collection.
The problem with transit data is that calculating a future schedule can require a lot of processing (especially if there are multiple routes involved in the rider reaching their destination) because, basically, the system needs to do a trip plan for each scheduled trip at starting point for the time range.
Google hints at this in their API regarding the alternatives parameter
alternatives — If set to true, specifies that the Directions service may provide more than one route alternative in the response. Note that providing route alternatives may increase the response time from the server.
Also, the different future departure times may actually be different routes or combination of routes (e.g. where multiple routes may come together on the same street for a while - for instance, near a college campus or other transit hub)
In order to get the underlying route data that would have the actual stop times you are looking for you would need to download the transit agencies' GTFS data directly and process it yourself (check our GTFS Data Exchange). This is what your competitors are already doing (e.g. Transit App, Moovit, etc.). There are packages that will do some of this processing for you (e.g. One Bus Away). However, even with the use of existing libraries, there is some heavy lifting involved here (from a development point of view).
As a final note, if you want to pursue using google maps directions api you wouldn't need query it for each minute within a time-range in order to get a series of departure times. You should be able to make a series of calls with the departure time set just past the departure time you got back in the previous call. For example, if the first trip time was 1:00pm set departure_time to 1:05pm and request again, then if the second trip time was 1:20pm set the next departure_time to 1:25pm and request again, and so on to build your list of future trips.
Okay. Firstly your question is not in the right spirit as stackoverflow demands. Check at google's developer console , API section and check if they offer any such API to give you all transport schedules in 24hrs or not ? If there is any such API then good, you can hit that but if not then I am afraid you wont be able to get it unless you hit API after some intervals.
Another suggestion is that , you can try yahoo or bing maps and check if they have any such API for your query.
I'm new to geocoding so I'm not certain this is even the question I should be asking, but all of the other discussions I've seen on this topic (here and on the Google API forum) are so application specific that I feel like I might be missing a very elementary step - I don't need to know how to implement a store finder - I need to know if I should.
Here is my specific situation - I have been contracted to design an application wherein we will build a database of shops (say, independently owned bars and pubs). This list will continually grow and change as shops close and new ones open. The user can enter his/her point of origin (zip code or address) and be shown a list or map containing all the various shops within a given radius in order of proximity.
I know how to deliver these results from a static database:
One would store the longitude and latitude as columns for each row and then just use that information to check distances.
But I have inherited an (already fairly large) database of shops which have addresses but not coordinates - so I'm not sure what the best way to get those addresses is. I could write a script to query them one at a time against google geocoding, I could have a data entry person manually look up the coordinates for each one and populate the data that way, or maybe there is a third option I'm not aware of.
Is this the right place to be asking this question? Google Maps Geocoding doesn't host a forum of their own, but refers people to Stack Overflow. Other forums on the net dealing with this topic are all relating to a specific technical question but no one seems to be talking about it from a top-down perspective (ie the big picture).
Google imposes a 2,500 queries per day limit on free users and a 100,000 queries a day limit on paid ones - neither of these seem to be up to the task of a site with even moderate traffic if, every time a user makes a request, the entire database (perhaps thousands of shops) are being checked against Google's data. It seems certain we must store the coords locally but even storing them locally, there will have to be checks against Google in order to plot them on a map. If I had a finite number of locations (if, for example, I had six hardware shops) and I wanted to make a store locator, there would be a wealth of discussions, tutorials, and stack overflow questions available to point the way for me, but I'm dealing with a potentially vast number of records and not sure how to proceed or where to begin.
Any advice would be welcome - Additionally, if this is not the best place to be asking this question, a helpful response would be to indicate a better place to post it. I've searched for three days but haven't found what looks like a good resource for asking such subjective questions.
The best way of course would be when you use a geocoding-service to get coordinates and store the coordinates in your DB. But it's not possible with google's geocoding-service, because it's not permitted to store geocoded data permanent.
There are free services without this restriction, some keywords to search for: mapquest, nominatim, geonames(but these services are less accurate than google)
Another option would be to use a FusionTable. The geocoding would run automatically(but the daily limits are the same as for the geocoding-service). The benefit: the geocoding is permanent(you can't access the locations directly by e.g. downloading the DB-dump), but you may use the coordinates for plotting markers(via a FusionTablesLayer) or filtering(e.g. by distance)
The number of entries shouldn't be an issue, 100k is no problem for a database
I want a list of locations (coordinates) for all possible colonies/neighborhoods of some Indian cities. Take for example Delhi. Can this data be obtained with the Places API?
The only thing that comes to my mind is to use a query like -
https://maps.googleapis.com/maps/api/place/search/xml?location=28.540346,77.210026&radius=500&types=administrative_area_level_1|administrative_area_level_2|administrative_area_level_3|locality|neighborhood|street_address|sublocality|sublocality_level_4|sublocality_level_5|sublocality_level_3|sublocality_level_2|sublocality_level_1|subpremise&sensor=false&key=MYKEY
and then keep changing the radius by 500 till the whole city is covered.
Is there a better way of doing this?
Given how often you would need to do this for your map, since caching that data goes against the terms of service, this is not a great approach. If you map gets any decent usage, you'll rapidly hit your quota. Plus you're only get center points of the colonies/neighborhoods. I'd recommend trying to find another source of that data you can download. The Places API was not designed with this in mind.
My client wants some of the functionality of Google maps namely:
- geocoding
- generating maps with points based on postal code or long.lat
- optimal trip mapping
Their issues with Google maps
- cannot control outages
- postal codes are sometimes inaccurate or not updated frequently for Canada/UK
- they have no way to correct inaccurate information
They would prefer to host the mapping application themselves, but will require postal code updates.
Can anyone suggest such a product?
thanks
"cannot control outages - postal codes are sometimes inaccurate or not updated frequently for Canada/UK - they have no way to correct inaccurate information"
Outages
hosting your own mapping is the only way to control this, but you would be very very hard pushed to beat Google Maps / Bing Maps uptime over the last 5 years. Take a look at the following:
OpenStreetMap for the road imagery data, this is open source data very good in the UK (Im not sure about canada) and you can make your own changes and submit them (or just change the data you have downloaded)
Geoserver, Mapnik or MapServer will read openstreetmapdata and create the image tiles needed to create your own maps in whatever style you wish. Depending on if you dont want all countries and all zoom levels these products can create all the tiles you will need in advance, but usually they have to be created in real time and cached. You need a BIG fast server to manage tile crunching
Openlayers or Leaflet are open source javascript mapping platforms that will display your tiles for you
Obviously this is just for road maps, aerial imagery would cost you an absolute fortune.
Post Code Data
Many people do not realize that UK postcode data for latitude and longitude is now completely free and available to download every quarter from the official source (ordinance survey) http://www.ordnancesurvey.co.uk/oswebsite/products/code-point-open/index.html.
This is the same data source Google will use and there is none better but it will always contain inaccuracies and always be a few months out of date.
Finally
Hopefully that answer the question you asked and gives you information to inform your client. Now for the question you didn't ask "Is this approach good value to my client?".
I won't presume to know your business or client, however what I described above is possible but with one to many months of work involved to get it all working together and even then it wont have any where near the performance or uptime of something like google /bing maps and only offers a small subset of their features.
I think you're looking for something like Caliper-It's a very custom, and I would expect expensive, solution. Not suggested.
http://www.caliper.com/GISMappingSoftwareDevelopment.htm
One solution could be to use two different mapping services and compare their results, this way there's a much better chance the data is accurate. You can also fix inaccurate data by creating a system which acts as a barrier between the API and your user, where data you know is inaccurate is corrected before it's displayed. Not sure exactly what you're doing though, so this might not work for you.
Is trip mapping/routing the basic functionality you want to do?
Before rushing into rolling your own, I'd suggest a good think about the consequences of doing so. The first that springs to mind is whilst the pros are that you can now control your data, the cons are that you now control your data.
So you are going to have to consider where and when you get updates and the processes you are going to have to employ to keep your maps in sync with the rest of the world. There are a lot of headaches involved in these things which is why so many people use externally hosted solutions such as Googles.
I'm looking for examples of how to create my own page/site with google maps API.
Specifically, if anyone knows of example for road trip. Let me explain:
1. Let's say I'd like to drive from california to maine, obviously I'm not going to get there in a day.
2. Now let's say I'd like to leave at 5p.m drive all the way into the night, 11p.m - 12.am for example, so it would be nice to see where I can be after 5, 6 hours of driving.
3. Standard google (yahoo, bing, etc.) don't have that option (unless I don't know how to enable it), but they only give you total time, for example 30 hours. I can't nor I don't want to drive for 30 hours straight. I'd like to see where I can be after x hours.
anyway, this is getting to long, so if anyone has a collection of good/nice/cool examples with sample code, please post it.
Based on the time you want to leave, the time of arrival as given by your api you can calculate the average speed.
Using the average speed, you can know how many kilometers you can drive in a given time. If you know how many kilometers, you know where you are.
It looks like if you are using the API it returns information about each step (distance, time, etc.). You can then use that information to show the user where they will be based on what time they started. API Information here.
