vGIS Admin Portal scripting language (KB-TT010)

vGIS supports custom post-processing configuration for GIS data. The post-processing is handled through scripts applied to data sources. The foundation of vGIS scripts is LUA programming language.

Data processing takes the source object (specific to each data source type - e.g., placemarks for KML and featured for ArcGIS) and applies configuration settings to it (see below). The transformation produces a unified destination object (see below).

Scripts are executed after data is processed. At the logical level, scripts have access to source, destination and configuration objects.

Notes and Recommendations

  • Use local keywork for new variables instead of global (by default)
  • To work with attributes in destination object use GetDynacmicProperty(name,defaultData)/SetDynamicProperty(name,value) methods
  • To work with GUID use examples below
  • All measurement units in destination should be in meters, and the script must call ToMeters() function when using values from MeasuringTypeField or MeasuringTypeValue.

Examples

Example 1

Treat the value of "1" in the depth field as null and use the default depth instead.

if configuration.DepthField ~= nil and configuration.DefaultDepth ~= nil then
    local nullMarker = '1';
    -- Use default depth if depth field contains null marker or if such field doesn't exist.
    local depth = destination:GetDynamicProperty(configuration.DepthField.FieldName, nullMarker);
    if depth == nullMarker then
        destination.Altitude = configuration.DefaultDepth:ToMeters();
    end
end

Example 2

Treat the value of "1" in the Diameter field as null and use the default diameter instead.

if configuration.ObjectType == ObjectTypeNew.Line and configuration.ObjectTypeConfiguration.DiameterField ~= nil and configuration.ObjectTypeConfiguration.DefaultDiameter ~= nil then
    local nullMarker = '1';
    -- Use default depth if depth field contains null marker or if such field doesn't exist.
    local diameter = destination:GetDynamicProperty(configuration.ObjectTypeConfiguration.DiameterField.FieldName, nullMarker);
    if diameter == nullMarker then
        destination.ObjectTypeNewData.Diameter = configuration.ObjectTypeConfiguration.DefaultDiameter:ToMeters();
    end
end

Example 3

Code examples for a single layer.

  • The layer is detected using the destination's LayerFullId
  • ROOT layer isn't included in the full Id
  • The full id of the layer can be identified at the feature layer configurations -> Statistic page
if destination.LayerFullId == 'grouplayer19/featurelayer20' then
-- YOUR CODE HERE
end

Example 4

Working with GUID type.

GuidClass=luanet.import_type('System.Guid')
guid_cons=luanet.get_constructor_bysig(GuidClass,'System.String')
destination.SceneLayer = guid_cons('11111111-1111-1111-1111-111111111111')

Example 5

Changing geometry dynamically.

local geoidShift = -0.45
if destination.GeometryType == GeometryType.Polygon or destination.GeometryType == GeometryType.Line then
    for i = 0, destination.Geometry.Points.Count - 1, 1
        do
            destination.Geometry.Points[i].Altitude =  destination.Geometry.Points[i].Altitude + geoidShift;
    end 
elseif destination.GeometryType == GeometryType.Point then
    destination.Geometry.Altitude = destination.Geometry.Altitude  + geoidShift
end
