I have a KML file that I exported after making my own Google Map. I was wondering if anyone knows a way I can get this map into BigQuery as a table of the Precinct name and the coordinates of their borders? Thanks in advance!
You can't load KML directly into a BigQuery GEOGRAPHY column. But BigQuery does support loading from WKT, WKB or GeoJSON.
So you'll have to first convert the KML into one of the above formats, perhaps using GDAL?
After that you can run a bq load. Alternatively to a load, it also works well as an external table, for example with WKB embedded as one column in a CSV.

I have a geoJSON file that needs to be edited. For example, I need to do a Find and Replace operation. However, I cannot even open the file (150 MB) in some applications. With TextEdit (I'm on a Mac), I can open the file, but the app stops responding and freezes almost immediately when I try any Find and Replace operation.
The file contains data (Points) that I'd like to map (I think I will use Leaflet), so eventually I need to transfer the file to my server. Given the size of the file, will I run into any problems there and then mapping the points in a browser?
Any advice or pointers on what to do would be appreciated.
Check out this link on replacing text from the command line. You should be able to use sed to replace those instances without having to load it in memory (I think).

I am currently invested in a project to implement marine charts and maps into our custom Google Maps application. However, I am quite unsure of how to actually go about doing this. I would like to use the NOAA ENC data from here:
http://www.charts.noaa.gov/ENCs/ENCs.shtml
What I would like to do is use this data to display the charts on Google Maps. Does anyone have any ideas/tips/insight on how to do this?
Apparently there is an open-source reader which plugs into common utility (ogr2ogr) which allows you to convert the data into shapefile format:
http://home.gdal.org/projects/s57/
Once you get the data into shapefile format, then turning it into tiles is a well-understood problem. Here is one blog posting of one way someone did it:

I just started developing a Google web app, may I know what is the best way of storing data? Is it by using scriptDB, spreadsheets or JDBC?
You can take the hard work out of working with data storage by using this library:
http://www.harryonline.net/scripts/objdb-storing-data-with-google-apps-script/482
Using this library, you can work both with spreadsheets and JDBC databases, and easily switch if you later change your mind.
If you want to modify the data directly, then you can save data in spreadsheet and build apps based on spreadsheet data. If you store data in ScriptDB, you can not edit data easily. It all depends on your requirements.

Does anyone know where I can find a pregenerated database that has all zip codes and their corresponding city and state?
EDIT: Or is there any webservice that provides this functionality?
Here is one for the USA https://web.archive.org/web/20101126192032/http://pablotron.org/files/zipcodes-csv-10-Aug-2004.zip
It's a CSV file that maps zipcodes to a latitude/longitude coordinate and a city name. The data is under a CC BY 4.0 license but it hasn't been updated since 2004.
Assuming your MySQL frontend is phpMyAdmin, see how to import CSV file, after that, delete columns you don't need, or do it before importing in lets say Excel.
How about this?Not precisely what you asked for, but if your app has internet connectivity, it's probably what you want; never wrong and not your problem.~~
The link above is dead, but this might do the trick if a static database is OK.

Hope someone can advise,
I would like to be able to use google map API to find all Zip codes/cities with x Miles of a point.
Has anyone done such a thing with google map or maybe some other type of service.
Would love to know if so how you have achieved it !
Thank you if you can advise.
There's nothing in the Google Maps API that can help with that, and I've never heard of any such service that could be mashed up with a Google Map.
What you could do is obtain a list of the locations of all the zip codes. Do a web search for [free zip code database] there are lots of them out there. Put it on your server then write your own server script to search it.
