I have been using the following licensed products to publish my GIS data on web.

  1. web server: windows 2008 R2,
  2. GIS desktop: ArcGIS desktop,
  3. GIS web server: ArcGIS server,
  4. API: ArcGIS API for JS,
  5. Database: Oracle with ArcSDE,
  6. IDE: Eclipse.

But now I want to switch altogether to open source world mainly because of freedom. Fortunately there is plethora information about open source on web but unfortunately are confusing me a lot. There are soo many products like geoserver, mapserver, openlayer, geotool, vaadin, geomajas, uDig, GRASS etc etc. I am not able to related these products with the one I am already using.

Can someone please relate the equivalents?

There are either too many possible answers, or good answers would be too long for this format. Please add details to narrow the answer set or to isolate an issue that can be answered in a few paragraphs.If this question can be reworded to fit the rules in the help center, please edit the question.

As it stands your Question is far too broad - even asking for the Open Source equivalent of one would be too broad. I recommend that you research each and then come back to ask a more focussed Question around a mandatory requirement that you have for one product tier. – PolyGeo Apr 8 '14 at 4:11
Note that Eclipse is open source, its not an ESRI product. So that one is already OK! – BradHards Apr 8 '14 at 4:14
I do not know enough to make an answer, but the search engine returns quite a few results for open source alternatives to ArcGIS (scroll down the page). – ignis Apr 8 '14 at 6:25

Even though the question is too broad, it is answerable in a general sense.

In the Open Source world, there are many equivalent tools which can be used for a particular function. Which tool or application to use, would depend on you are your experience with it. I'm just giving the most popular tool or equivalent applications.

  1. web server: Any Web Server will do. Most People use Linux Servers with Apache
  2. GIS desktop: Qgis, uDigg and Grass
  3. GIS web server: GeoServer, MapServer etc
  4. API: OpenLayer, Leaflet
  5. Database: PostGresql with PostGIS extension
  6. IDE: Eclipse is already open source, but even a simple Text editor will do.

You should also know that you won't get one to one correspondence between the ESRI and Open Source Equivalents. For example. if you expect that you can publish a Map like you do with ArcGIS Desktop and ArcGIS Server, you will have a hard time. The Open SOurce Web Services are quite different from ArcGIS Server's Map Services

Dear Devdatta, Thanks a lot. Being specific and sensible for a beginner is really difficult when there are so many options in the market. But your answer definitely cleared a lot of my doubts. – Zia Apr 9 '14 at 11:11
@Zia: Glad to help you out. – Devdatta Tengshe Apr 9 '14 at 11:20
Dear Devdatta, Can you please suggest some online tutorials also where I can get a good basics of all these tools? Since for ESRI, there are good tech support available but for FOSS all the supports are independent and I am not able to draw a basic sketch in my mind. Thanks a lot. – Zia Apr 9 '14 at 11:44
Unfortunately, Open Source is not an Monolithic entity like ESRI, and there isn't one single place where you could get all the information. You need to search at various locations and individual websites. The closest you could get is a site like GIS.Stackexchange, which has information about various different softwares. – Devdatta Tengshe Apr 9 '14 at 12:06
Thanks a lot. I'll stick to GIS Stake Exchange :-) – Zia Apr 9 '14 at 15:08
