Open source and open source solutions for GIS projects

Get rid of the constraints of free map development package, the cost of rejecting business map software, efficient, accurate, complete is our open source solution of the purpose.

1. Map Grid Data Open source

Using our self-developed multi-source map Downloader, our open source solution can support a variety of free internet maps, which is also available in the intranet environment.

We currently offer open source solutions that support Baidu maps, Google Maps, Bing Maps, world maps, and related special maps.

2. Map vector Data Open source

As we all know, the most widely used in China Baidu Map has its own Mars coordinate system, do not use a special method is difficult to convert existing SHP and other vector data into Baidu Mars coordinate system.

We have a complete solution for this industry-proven challenge:

(1) WGS84 coordinates accurately converted to Baidu latitude and longitude coordinates (do not use Baidu API, precision in the decimal point six digits).

(2) Convert the SHP layer in the WGS84 coordinate system into the SHP layer in the Baidu Mars coordinate system.

(3) Baidu latitude and longitude coordinates and Baidu metric coordinate with each other conversion.

3. Map Service Open Source

Use a proven open source GIS solution: GeoServer (server) +tomcat (middleware) +postgis (database) +udig (desktop) for map editing, storage, publishing, and service.

We are not only limited to the use of existing open source software, based on a number of optimizations and improvements:

(1) Customized two times based on GeoServer, such as trajectory optimization query.

(2) Self-developed a set of comprehensive data batch automatic storage, release tools, eliminate the frequent switching between the software, reduce the use of GIS knowledge of the difficulty of personnel.

(3) Self-developed tile cutting tool, support more customized requirements, such as timing transduction and other needs.

(4) Independent Study of various tile format call methods, not only for the traditional PNG discrete map support, ArcGIS provides a bundle-type compact tile is also supported.

4. Open Source Map Development

The development framework on which our products are based is open source and does not require any commercial development environment.
