I am relatively familiar with most of the GIS stuff. I develop GIS applications as well with open source offerings. Still I find some lapses in my theoretical knowledge in GIS. What resources can you propose which might be good for an advanced GIS learner with a touch of software development?


One area I think I am weak in is coordinate systems and the theory behind coordinate systems.

Update: "I will mostly appreciate if you could point out one or two books as well"

    This site's not a bad start :-).

    I think the question is too open ended and you'd get better answers by pointing area(s) you know you are thin in. What is "basic" for one is "advanced" for another. For example old timers might consider NAD27-83/WGS84 datum transformation a fundamental everyone must be at least a bit familiar with, but many new practitioners who are none-the-less professionals with years of experience will say "a datum what??".

  • Thanks whuber, please share with me any resources such as books etc. I can refer to, questions thus come up, I will be able to post here.

    @pic Another way to use this site, besides asking specific questions, is to perform focused searches. For instance, since you have expressed an interest in coordinate systems, you might look at all the questions with the coordinate-system tag. That would give you a sense of what issues come up and are considered important by GIS practitioners. The answers are often informative and linked to other useful Web resources.

    For coordinate systems, a good basic understanding can be found in the ESRI publication (as much as I don't like to say it) Understanding Map Projections. For anything more involved than that, look at the book by John P Snyder is a heavy but useful text. Look at the PROJ4 site. +1 @Zachary (excellent reuse of existing content). Apr 21 '11 at 21:06

Since you included the tag of "postgis" I assume that is one of the software/database package's you are interested in.

The book "PostGIS in Action" was just finalized, printed and started shipping about a week ago. At $50, it's not a bad price. It appears to be quite comprehensive @ 520 pages, and could be a valuable reference guide for anyone interested in PostGIS and its various components. You can download the first chapter for free, which also includes a brief table of contents to give you an idea of what it covers.

    I've read the book from end-to-end and it's excellent. I highly recommend picking it up. The time you save yourself will more than make up for the cost. Apr 21 '11 at 21:13
  • Agreed, picked it up myself and it is very good. Apr 22 '11 at 11:11

GIS Tutor is a good starting point


specifically PostGIS - the wiki is a good starting point


  • Thanks Mapperz, I will definitely refer those sites. I will mostly appreciate if you could point out one or two books as well. Thanks again.

You also want to think about what your real interest is. Do you want to be a GIS developer versus a analyst in a particular field. You will see many places want to have a GIS person that has skill-sets in development as well as GIS.

But you can be a strong GIS user if you study Landscape Architecture, Civil Engineering, or even just starting as a CADD Analyst like me.

There are a lot of good generalist out there in the industry; who can just setup a basic spatial DB, slap a web-ui on a OpenLayers page consuming Bing/Google and be happy with that. Where you see the people who are most passionate about GIS is the ones who have it just as a tool in there box. Knowing your data domain is a great place to grow, to know what you want to build and support to be able to anticipate needs.

Core Hardware and Software are important in many areas, because if you can't see how you systems need to grow, then you won't be able to sustain the efforts.

What do you really want to do?
