- Feature layer—A layer that references a set of feature (vector) data that represents geographic entities as points, lines, and polygons.
- Raster layer—A layer that references a raster or image as its data source.

What are GIS layers?
In ArcGIS, layers are collections of geographic data. Layers reference a data source, and if ArcGIS Pro interprets data as spatial, the data’s properties and attributes specify how the layer draws on a map, scene, or layout. Data gathered in a layer is represented with points, lines, shapes (polygons), or surfaces.
What are map layers?
Layers are mechanisms used to display geographic datasets on maps. They contain groups of points, lines, or area (polygon) features and define how a geographic dataset is symbolized on a map. Map layer forms the fundamental unit while doing analysis on maps.
What are GIS data layers?
Layers are the mechanism used to display geographic datasets in ArcMap, ArcGlobe, and ArcScene. Each layer references a dataset and specifies how that dataset is portrayed using symbols and text labels. When you add a layer to a map, you specify its dataset and set its map symbols and labeling properties.
What is a leaflet example?
The leaflet, also called a folded flyer or brochure, is a product printed on a single sheet that’s folded once or more. For example, in the image below, you can see a leaflet in A4 format with 2 folds: this creates 3 panels on the front and 3 on the back, 6 panels in total.

What are the five GIS layers?
GIS has five layers, which are spatial reference framework, spatial data model, spatial data acquisition systems, spatial data analysis, and geo-visualization.
What are the five steps of GIS?
The five steps in the analysis process are:
- Frame the question.
- Explore and prepare data.
- Choose analysis methods and tools.
- Perform the analysis.
- Examine and refine results.
How can I add layers to Esri leaflet?
The first step to adding layers would be to download the JavaScript library at ESRI’s GitHub account here (the file is esri-leaflet.js in the dist folder). With this piece in hand, adding layers is easy.
Can you add a layer to an ArcGIS map?
A lot of government agencies and other institutions make map layers available through ArcGIS Server map services. The United States Geological Survey’s National Map Program, for example, makes services available for adding basemap, topography, weather and other layers.
Which is an example of an ArcGIS map?
Using the National Map as an example: browse to this link where you can see the different layers available. You can see that they offer several types of layers including tiled and dynamic map layers (feature layers will be covered in a future post).
How to add tiled layers to a map?
Tiled layers are static layers that have been pre-generated and dynamic layers, as you might guess, are generated dynamically. Adding both types of layers uses the same basic syntax: Where URL would be copied and pasted from the National Atlas web page.
