GIS programming vs GIS Analysis

Sajid Pareeth — Wed, 13 Jan 2010 12:49:21 +0000

Day before while in a project meeting, an interesting topic came up as my fellow mates said, It would have been better if i knew coding. I am not a coding expert, but i understand the working and can find new tools available in the (open)web, mange to install them too. But looks like its not sufficient and we need to really sit and code to understand the effort they take to develop.

Yes you are right , no matter how you get the thread or how you learn ,

You are the creator (the programmer!!!)

Kosi river course change in MODIS images

Sajid Pareeth — Sat, 30 Aug 2008 05:30:38 +0000

I found this MODIS images in NASA news room, which shows the Kosi river course from Nepal to Bihar , India before the flood and after the catastrophe. Its really surprising the way river changed its course suddenly and decided to take this new path which was originally its course 200 years back.

Master’s thesis video

Sajid Pareeth — Thu, 31 Jul 2008 02:30:09 +0000

I did my thesis on developing a web based GIS for online digitization using OGC specifications and open source tools. Title is ‘OGC compliant solution for online digitization using open source tools’. The idea is to facilitate collaborative research in Land use Land cover change studies by giving researchers a platform to digitise training sites on satellite images in a common web platform.
The tools used are Deegree server, Mapbender and PostgreSQL. The system is empowered with the OGC specifications like WMS, WCS and WFS-T. The transactions where the user defined geometries get saved in the backend database is done using the WFS-Transaction specification of OGC.

Below given is the video of final presentation , Thanks to my buddy Gabriel Sanya.

I want to improve the system by adding more tools for image processing like histogram or scatter plot where user can analyse his training sites online. It will help small organisations to do Land cover classifications or to take part in such processes without having a proprietary software or image processing know how. I was thinking of giving services through this platform.

1) Organisations interested in doing land cover classifications or any other related task where they need to collect data from satellite images can request through the system by giving the details like study area, years of study, purpose.

2) After a request is filed, we will look for the available images and upload it into the system with associated layers if available. Then the researchers associated with the work can log in and start defining their training sites with proper attributes.

3) Once it is finished we will collect the data from the backend database and refine it and do the classification. Classified image can be published again so that they can comment on it for further iterations. Any additional services can be done on request.

I think this will work very well for organisation who doesnt want to set up a GIS and Remote sensing lab for small tasks.

Thanks to Dr Harini Nagendra for giving me this idea and her constant support.

Mapfish:decorated Openlayers

Sajid Pareeth — Sun, 27 Jul 2008 03:36:28 +0000

I admire the simplicity openlayers offers as it doesn’t have any server side dependencies. There are occasions i wish i had more tools from openlayers. Of course it offers loads of classes , we need to know Javascripting in and out in order to customise the interface. Mapfish uses an external javascript library called extJS.

Here comes the advantage of mapfish , a comparitively new release in the world of open source tools for geospatial. Mapfish provides both client and server (java and python). Client is built up on openlayers and added more functionalities. I tried out their demos , quite impressive especially the examples on geostatistics. We can use mapfish client with almost all other servers, and offers everything which openlayers has and more customised tools.

It uses the Geojson format for the geostat examples. I really liked this one and it has other potential applications like dynamic symbology . The GeoJson format is light weight and simple to handle, so quite fast in the application.
An blog on this by Bjørn Sandvik in his thematic mapping blog
I will give an example in the next post.
I would say we can compare the functionalities with that of new ArcGIS server 9.3 Javascript API.

Geoserver can serve WFS service in GeoJson format , What more can you ask for, So get ready for more applications using Geoserver and Open layers/MApfish.
Enjoy the freedom.
