TdhGIS
TdhGIS provides a robust and versatile set of tools for vector based spatial analysis. Everything needed to be performing spatial analysis within minutes is included in this easy to use software package.
Feature Summary:
Graphically create and edit geometric data, as with a CAD program
Import Shapefiles and OpenStreetMap data
Use raster images as background and a CAD drawing as an overlay
Color polygons based on user data values using either discrete intervals or gradients
Allocate point data to user specified buffers for points, polygons and multilines (e.g. find all gas stations within 1 mile of a highway)
Allocate point data to polygons. (e.g. assign structures to hydrological basins)
Allocate polygon data to other polygons. (e.g. allocate population data by census block to political boundaries)
Create thiessen polygons (e.g. for all hospitals within a state, define the areas closest to each hospital)

GeoGrid
GeoGrid is a lightweight GIS, a universal geographic information system with essential features, ready for immediate use via cloud, web, and mobile apps. It empowers any user, not just GIS specialists, to visualize, manage, and analyze spatial and business data through interactive, map‑based dashboards. Its configurable data model ingests and combines over 450 formats and data sources (e.g., FME integration), making it easy to collect, transform, and integrate geospatial and tabular information. Users can create eye‑catching interactive maps with OpenStreetMap backdrops, zooming into object attributes, linked documents, tables, and charts, and uncovering spatial relationships. Real‑time asset monitoring reduces costs and boosts efficiency, whether running standalone or integrated with other GIS systems. Collaborative editing allows multiple users, whether stationary or field, to update, add, or delete objects live.

OpenStreetMap
OpenStreetMap provides map data for thousands of web sites, mobile apps, and hardware devices. OpenStreetMap is built by a community of mappers that contribute and maintain data about roads, trails, cafés, railway stations, and much more, all over the world. OpenStreetMap emphasizes local knowledge. Contributors use aerial imagery, GPS devices, and low-tech field maps to verify that OSM is accurate and up to date. OpenStreetMap's community is diverse, passionate, and growing every day. Our contributors include enthusiast mappers, GIS professionals, engineers running the OSM servers, humanitarians mapping disaster-affected areas, and many more. To learn more about the community, see the OpenStreetMap Blog, user diaries, community blogs, and the OSM Foundation website. OpenStreetMap is open data: you are free to use it for any purpose as long as you credit OpenStreetMap and its contributors.
