Data Links


Data Links connects you to sites where we download background data for use in our software. We are not a data storage company, there are plenty of sites out there storing data for downloads. If you are like us, you have had a hard time finding the data you are looking for, so we put together some links. Along with the link is a guide to what useful data to get from this site.


To use data in GK Tech software, it should be downloaded in UTM Zone "xx" or if not an option try Lat/Lon. Also, all downloads should be in .SHP - Shape File, .TIF, .SID or .ECW formats. There are no guarantees that the data you download will work in our software, due to many variables in file encoding and projection. If you have problems please let us know.




Please drop us a line if you know of any other sites that you have found helpful for getting data and what data you are getting from that site. Data can be very local for your area, national or international, we will try to get them added to our Data Links page. Also, please let us know if any of the links are not working.

The US Census Bureau is a great supplier for basic county data such as Roads, Railroads, Waterways and Townships. The files to download are the “edges” files for Roads, Railroads and Waterways. The “cousub” file will give you useable Township data for most areas. Suggest using the “FTP” option for downloading.

-NOTE: You will need to know your Federal Information Processing System (FIPS) numbers for your State and Counties. We are sharing two links here, same code numbers, different formats.
