How to create interactive maps with GIS ?

Some free but useful software for working in GIS projects are : MapWindow GIS,Quantum GIS etc.

The steps for creating a Geo-referenced and informative spatial database( or database linked to spatial points) is the following :

a)Selection of Coordinate System

b)Creating shape-files(line for digitizing road,rivers etc;polygon for digitizing water bodies,plantations etc. and points for indicating cities,places etc.) 

c)Creating the attribute tables linked to the shape-files where columns represents different attributes and rows represents the sub-shapes representing different features of same shape(artificial ponds can be digitized with polygon shape-files and each pond can be digitized within single shape-file where each sub-shape will describe that kind of pond only) 

d)After relevant informations are entered into the attribute tables data-sets can be represented with the help of different colours or degree of colours or different styles.

Each of the above steps will be discussed in detail by using the MapWindow GIS software.

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 .
