Supported layers

The GISMapApp supports three types of layers and they are: Imagery Layer, Feature Layer, and Group Layer.

Imagery Layer

• Imagery and raster data are available on a web service.

• Depending on the server capabilities and requirements, various methods are available (tiled imagery, tile caches, dynamic imagery, map image, etc.).

• Pre-rendered images in grids that are organized by zoom levels for specific resolutions (e.g., satellite, terrestrial, topographic, etc.).

• The imagery layers that are supported include ArcGIS, Bing, Custom, Esri, GeoJSON, Google, Group of Layers, Mapbox, OpenWeather, OpenStreetMap, Particle Animations, TileJSON, WebMap, WMS, and XYZ.

  

Features Layer

• Spatially enabled data that contains features with geometries and attributes.

• Vector data is available in different formats (GeoJSON, JSON, KML, GML, etc.).

• Some providers incorporate details regarding the rendering of features, such as clustering, into the layer definitions.

• The feature layers that are supported include Custom, Esri, and GeoJSON.

  

Group Layer

• A specific type to group other layers.

• A layer can be configured as an overlay or basemap.

  • Basemap layer: A background layer where only single layer is visible at the same time.

  • Overlay layer: Multiple layers can be viewed at the same time, and they are stacked one on top of the other.

• There are common configurable options for all type of layers (Common options) and specific configurable options depending on the type of layer.
