Coordinate System Part 1

The first step in developing an interactive map linked to relevant data that you want to represent is to select the coordinate system with which you want to work.The tip is if you are working in a global scale use the global coordinate systems.
If you are working within a country use the local coordinate systems.If the scale of you work is within the district/state then use cadastral maps.
A single point can be represented by x and y axis of your paper,height and width of your room or even the global coordinate systems.Each of the representation will be correct but the resolution will be effected.In x and y axis of your paper the resolution will be best,in the height and width of your room resolution will be medium and in the global axis it will be poor.
That is why there are various types of coordinate systems and they are utilized based on the spatial scale at which you are working.

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 .
