Create Layer

  • Create Layer :
  • Steps to create layer:

    • click on point button on the left hand side of the screen, create new layer window will open.
    • Enter the layer name and you can also add attributes by click on add attribute button.

            

    • After clicked on create layer, layer will be created as shown on below screen.
    • You can search locations, add new datasets, Add/edit layers and style the map according to your choice and requirements. This tool provides us to generate this published map in PDF or as image format.

            In

    In GIS (Geographical Information System) vector data represent the information in points, lines and polygons.

    • Vector data is split into three types: polygon line (or arc) and point data.Polygons are used to represent areas, such

    as the boundary of a city (on a large scale map), lake or forest. Polygon features are two dimentional and therefore can

    be used to measure the area and perimeter of a geographic feature. Polygon feature are most commonly distinguished

    using either a thematic mapping symbology (color schemes), patterns or in the case of numeric gradation, a color gradation

    scheme could be used.

    • Line (or arc) data is used to represent linear features. Common examples would be rivers, trails and streets. Line features only

    have one dimension and therefore can only be used to measure length. Line feature have a starting and ending point.

    Common examples would be road centerlines and hydrology. Symbology most commonly used to distinguish arc features from

    one another are line types (Solid line versus Dashed lines) and combinations using colors and line thickness. In the example

    below roads are distinguished from the stream network by designating the roads as a solid black line and the hydrology a dashed

    blue line.

    • Point data is most commonly used to represent adjacent features and to represent discrete data points
