WebThe ontology of geospatial phenomena is a critical emerging research theme in GIScience (Egenhofer, 2004). According to Kuhn (2005), geospatial ontologies can be seen as ‘GIS at the type level’. That is, they should provide reasoning capabilities (spatial and non-spatial) about conceptual geospatial elements, similar to the reasoning ... WebTo create a choropleth map with a rate, ratio, or proportion, use the following steps: Expand a dataset in the data pane so that the fields are visible. Select a rate/ratio field . If you have rate/ratio values in a number field , you can change the field type by clicking the field icon and choosing Rate/Ratio.
