Is Their anything like stored maps from where I can get Latitude/Longitude from address and vice versa. Like a database file or something else other than web based services so that I will not have to be connected over Internet while calculating address from Latitude/Longitude and Counter-wise.
Thank You
EDIT : Just to be clear. We use Google API's to find out Routes between two Geo-Locations I need the Same Feature.
Nominatim ? [1] It’s one of the source for the OSM home page.
Source code is on github [2].

EDIT: I didn’t understand correctly. You can checkout OSRM : http://project-osrm.org/
Maybe you can check out Navit it is an open source offline routing and navigation application. They have a wiki over here which also explains a bit about routing.
I have not tried the application, but one of the features mentioned in the wiki is "adress and POI search".
There are several means of contact mentioned in their wiki as well, if you want to ask them about how they did.
You might also want to check out this list to find other interesting apps that provide offline map storage, routing and/or offline address search http://wiki.openstreetmap.org/wiki/Software/Desktop
This looks interesting as well: OSM Automated Navigation Directions.

In the old Maps URLs API, you could add "&dirflg=dt" in the URL.
Here's an example URL using the new API taken from Google's official pages here:
https://www.google.com/maps/dir/?api=1&origin=Google+Pyrmont+NSW&destination=QVB&destination_place_id=ChIJISz8NjyuEmsRFTQ9Iw7Ear8&travelmode=driving
In the Google official pages, I was unable to find anything related to sending it flags to avoid tolls so I'm not even sure if it is possible with the new API.
Does someone have any info to enlighten me with? Thanks for reading.
:)
This is not possible with the Maps URL in this version, but you can do this manually after loading the directions.
You can try this:
Load the URL. (eg.:
https://www.google.com/maps/dir/?api=1&origin=Google+Pyrmont+NSW&destination=QVB&destination_place_id=ChIJISz8NjyuEmsRFTQ9Iw7Ear8&travelmode=driving)
On the left part of the screen, click OPTIONS.
Under Avoid, check Tolls.
However, if you want this functionality to be in the parameters, you can send your ideas by going in the Maps URLs Documentation and click SEND FEEDBACK. Or you can submit this as a Feature Request in Google Issue Tracker
Hope this helps!
This is possible, but you have to use "undocumented" features.
Warning: Since these are not documented features, they probably aren't official and likely subject to change without notice. Use in production at your own risk.
tldr:
https://www.google.com/maps/dir/{origin}/{destination}/data=!4m3!4m2!2m1!2b1
Plug in origin and destination and it should load directions, avoiding toll roads.
Explanation:
Here, we are using Google's own data/options string (see: "data=") to get the desired functionality. It is meant to be used by the Google Map's web app itself to communicate options selected on the page. This article (and the ones following it) explain how to create your own "data=" strings to customize how the map is configured. It's quite comprehensive, but like I said above, its not an official feature.
I'm making a visualization using google maps. However, I have to make many direction requests to google maps.
Is there a way to "download" a section of a map, along with all its bus/car/bike routing information, so the direction requests can be done locally?
If it's possible, can you give a rough example to get me in the right direction?
Thanks :)
No there's no offline access to the Maps API, for either viewing tiles for associated services like routing/directions.
Additionally, you must always ensure the results of these types of requests are displayed on a Google map (which must be publicly available for free, according to the terms of service).
If you are looking for the ability to do offline routing with your own dataset, there are a number of open source routing engines available.
anyone can suggest what program / approach I should use?
I need to have a map like google map where I can display map, add marker polygon etc.
But I cannot rely on such online services as client is afraid that such service die off and there goes our system...
Have a look at lots of resources pointed in answers to these questions on GIS.SE:
GIS for the web
Steps to Start Web Mapping
You might want to look at Google Fusion Tables, or solutions like MapBox or CartoDB for quick, hosted solutions.
Willing to invest more time (and depending on your skills and language preferences) you could delve into PostGIS & GeoServer / Mapserver with a frontend of OpenLayers / Leaflet (or any other libraries). OSGeo-Live DVD might come handy for a quick and dirty review of most of these options.
Here are pure open source based web map and geo-location database resources. Google map or Bing map is wonderful, but they require business contract for commercial use. It is said that Foursquare recently switched their map tool from Google map to open source based Leaflet API which looks like the picture below. This map tools is quite great and recommendable.
web API for map : http://leafletjs.com/
Good place to start. Two resources below are not really used for developers, cause those are already included in leaflet javascript API.
Map style : http://cloudmade.com/
Map data : http://www.openstreetmap.org/
Geo location based on ip address : http://dev.maxmind.com/geoip/geolite
Can download free ip address & city mapping file, which can be used for custom mapping code.
I recommend http://mapserver.org/
You can create map files into you server...and you can connect to open source databases like PostGIS
I'm working on a delivery service that only delivers within certain ZIP codes (probably, but not necessarily, all contiguous). Given a list of ZIPs, how do I get a map on which those ZIPs' areas are highlighted or outlined?
http://www.udsmapper.org/
This should be exactly what you need.. for personal/non-commercial use only though...
If you have a list of zip codes you can even paste them into the system and they'll automatically map!
Here is their user guide too:
http://www.udsmapper.org/docs/NEW_Instructions_Creating_Service_Area_Map_10102014.pdf
Here are some links of some helpful sites:
http://benfry.com/zipdecode/
http://maps.huge.info/
http://maps.huge.info/blog/boundary_maps/
http://www.usnaviguide.com/zip.htm
I didn't spend very much time searching these sites, but it didn't look like they were sharing their databases. That's what you are going to need... A database that can give you the lat/long coordinate boundary of the zip code area. I don't believe neither Google nor Bing offer a service that does that conversion for you.
Once you are able to do that conversion, from zip code to lat/long boundary, it should be pretty straight forward in both the Bing maps control and the Google api. If you have more specific questions on the actual implementation, then just leave me a comment.
Is it possible to use my own map instead of google maps for my app. How can I do that...Where should I look?
I think you need Open Street Maps (OSM). I have a little GPS app (Maverick Pro) on my Droid, and it can use 3 types of maps: google, bing, and "OSM". The latter seems to be what you need:
http://wiki.openstreetmap.org/wiki/Main_Page
You would need a few things:
A source for data about your geography, in the US see the TIGER Line data published by the Census Bureau.
Software to render the geo data into maps that are visually meaningful, for example Mapnik. Use something like OpenLayers to generate the
movability and nice user features people expect.
Software to deliver the rendered maps efficiently to your users, ie TileCache.
There is a nice summary of this FOSS approach here: http://m.alistapart.com/articles/takecontrolofyourmaps
You may want to check out MapTiler, an open source map tiling tool for Google Maps (and other mapping systems) which runs on Windows and Mac OS X.
MapTiler will automate the tiling process for you through a simple GUI wizard, and in addition, once the tiling process is finished, it will also generate a simple HTML viewer where you can see the results immediately.
Custom Map Tile Overlays are quite an advanced topic in the Google Maps API (even the documentation will warn you in red about this). However, I am sure you will be able to use and understand the HTML viewer of MapTiler.
PostGIS, Geoserver, GeoWebCache, OpenLayers, + GeoEXT gets you all the software you need.
Data is up to you and some of the examples above are good ideas.
