What is ToolMap?
ToolMap is a cost-free, open-source software dedicated for digitizing data and producing complex multi-layer GIS projects.
It was developped in response to the need of easily creating projects with:
- A faultless and accurate topological structure.
- A correct and homogenized semantic attribution.
It was developped in response to the two most reccurent problems given by such maps:
- The topological structure
- The semantical meaning
How does it work?
ToolMap perform its duty based on two basic and undissociable principles:
- The data model describing the nature and spatial relationships between the possible different features.
- The digitizing process allowing only two types of geometries, lines and points to represent all two-dimensional “real-world” objects. No polygon layer exists in ToolMap; they are built from the combination of lines delinaeting surfaces. Digitizing all lines, line feature (strictly speaking) and borders of polygons within one single layer yields the following advantages:
- No redundancy in the digitzing process: geometric shapes referring to multiple object types are digitized and stored only once.
- Perfect match between geometric shapes occurring in different thematic GIS layers: all objects are extracted from the same construction layers.
