4. GIS

GIS or Geographic Information System in OpenBrIM provides users geographic data essential for analysis and design of structures.

Go to Geographic Data in OpenBrIM App and draw a polygon on a specific location.

Figure 4.1: Geographic Data Map.

The selected location will generate a 3D elevation model.

Figure 4.2: 3D elevation model.

In Settings > BrIM, GeoData object contains objects (child elements) that provide specific geographic data regarding selected location.

GeoPoint

These are objects that provide the longitude and latitude of defined boundary of the area.

Example:

<O T="GeoData">

.

.

<O T="GeoPoint" Lng="-121.06839179992676" Lat="38.904927027872844" />

</O>

GeoElev

These are objects that provide the surface elevation of the selected area.

Example:

<O T="GeoData">

.

.

<O T="GeoElev" Lng="-121.06839179992676" Lat="38.88969670232407" Elev="1332.0209973767667" />

GeoTri

These are objects are used to represent the meshing in between GeoElev objects.

Example:

<O T="GeoData">

.

.

<O T="GeoTri" P1="0" P2="1" P3="33" />
