Five GIS Objectives That Can be Achieved Through the Attribute Table


Attribute Table

Pre-requisites

Attribute Table is a table where georeferenced data is stored for retrieval through geo-database. The data stored in the attribute table is used for the preparation of maps or geodatabases. When a shapefile is created a table can be connected to this file where relevant and related data of that feature can be stored.
This data can be later used as a geodatabase or to create choropleth maps or any other related geospatial documents.

To create an attribute table at-first shapefile needed to be created. There are three types of shapefiles: Point, Polyline, and Polygon shapefiles. Pont is created to digitize the location of a city, building, tourist spot, etc. Polyline shapefile is used to digitize rivers, canals, roads, rail lines, etc.

Polygon is used to represent lakes, water bodies, watersheds, etc.

Under each shapefiles, there can be many shape attributes. Normally for same kind of geographical features single shapefile is created. For river bodies in a map, only one polyline shapefile is required to be created under which all the river bodies are digitized as shape attributes.

After all the shapefiles and their shape attributes are created the next step is to create the attribute table or table editor. In this tutorial, we show how to achieve five different GIS objectives through the attribute table.

Software used: MapWindow 5 (open source).

Geospatial Jobs Portal : If you are in GIS subscribe to this newsletter

In recent years, India has graduated thousands of students in the field of GIS and Remote Sensing. The issue is that these graduates are unable to find work in their field of expertise. On the other hand, many GIS start-ups have been launched. Employees with desired GIS expertise are scarce in these organizations. Today, I'd like to propose a newsletter that serves as a link between start-up companies looking for ideal employees and recent GIS graduates. The URL is https://geospatial.substack.com/?nthPub=321 This newsletter publishes Situation Wanted opportunities in the field of GIS on a regular basis. Thanks, @Mrinmoy

Five steps to convert paper maps to digitized data driven interactive spatial application

Image
Any paper maps can be converted into the digitized data-driven interactive geospatial application by following the five steps as given below : 1) Scan the map into TIF 2) Import into DIVA-GIS 3) Create shapefiles for Placemarks, Pipelines or Roads or River and Some Area like Ponds, lakes, stadiums, etc. 4) Create Attribute Tables linked to the shapefiles 5) Export the tables and the shapefiles into an AppConverter to produce interactive Geospatial Application The entire procedure or the steps of digitization of maps by DIVA-GIS is explained in the presentation that can be accessed by clicking in the link . or view the video about the same presentation. If any terms like shapefile or attribute table are not clear or known to you then see this presentation .
