QGIS (http://www.qgis.org/zh_CN/site/) is the most commonly used free open source software for analysis and visualization of spatial data. It is user friendly, well-documented, equipped with hundreds of tools, and enables implementation of user's algorithms.

SAGA GIS (https://sourceforge.net/projects/saga-gis/) and GRASS GIS (https://grass.osgeo.org/) are also worth to consider. They can be installed as standalone, but they are additionally integrated in QGIS.

Hi Mudavath!

I think it is always worth playing around with R. It is a bit of a steep learning curve but if you can find someone to help you get started it is not that hard.

• R (Base Package):

https://cran.rstudio.com/

• RStudio (GUI for R):

https://www.rstudio.com/products/rstudio/download/

• Spatial analysis:

https://cran.r-project.org/doc/contrib/intro-spatial-rl.pdf

Also, you can share and publish datasets and analyses in a way that anyone can use it without paying loads for software.

I agree the response of Tomislav, QGIS and SAGA GIS are the most commonly used free software.

Hi,

GRASS GIS is also very powerful and interacts with R and allows for scripting and automatisation.

it is excellent for raster analysis.

https://grass.osgeo.org/

Best,

You can try Diva GIS as well. It is simpler and good for biodiversity analysis

https://www.diva-gis.org

GeoDa and GeoDaSpace are also good freeware alternatives:

http://spatial.uchicago.edu/software

You can try GEO DAT , is a software for spatial analysis

I concur with Selim that the best software is ArcGIS to do the kind of analysis required though it is a Professional software - with relatively affordable versions. The free software usually have limited operations and affects the map output accuracy and quality - neccesary for informed decion making . See ESRI @; www.esri.com

Thank you,

I think q gis is best for all this work. Here you can add so many tools and do your spatial analysis.

Hi Mudavath!

I highly recomend you use R for spatial analysis. Here i attach you two references that may help: - https://www.researchgate.net/publication/258151270_An_Introduction_to_Mapping_and_Spatial_Modelling_in_R

- https://cran.r-project.org/doc/contrib/intro-spatial-rl.pdf

- In my opinion "raster" library is very useful, almost you can do the same as with others not free sofwares as ArcMap: https://cran.r-project.org/web/packages/raster/raster.pdf

And also, as others mentioned above, QGIS is a good tool. Here you can find a tutorial that can help for your first contact with it: http://www.qgistutorials.com/es/ 

Good luck!

Hi Mudavath,

If you are working with spatial ecology or spatial statistics SAM is very good and simple to use. Spatial Analysis for Macroecology.

Andrea

Thank you every one for giving your valuable suggestions.

Dear Mudavath,

you have a lot of way to go with this list :

https://en.wikipedia.org/wiki/List_of_geographic_information_systems_software

But for me, according to your objective, you can use especially this softwares :

Qgis :

Grass :

SagaGIS :

https://sourceforge.net/projects/saga-gis/

Good work and progress...

Have a nice day,

Dear Mudavath,

I believe ArcGIS is the professional and powerful software for such analysis.

Regards

Hi Mudavath,

If you use Python, you can try Pysal for spatial analysis (https://github.com/pysal/pysal). For regression based methods, you can use GeoDa and GWR software.

GeoDa: http://geodacenter.github.io/index.html

GWR: https://gwrtools.github.io/ 

QGIS is always a good choice as well. 

Qunshan

Qgis will the best open source option 

Hello Mudavath,

Qgis and R should be enough

You can try QGIS and Grass

Pl. contact my research partner Dr.B.D.Madurapperuma of Hombolt uni.USA for this regard

 Yes,QGIS is better. But you can get more information from our research partner Dr.B.G.Madurrapperuma of Houlmbolt university USA 

I advise you Grass Gis, QGIS and Mapwindow.

In addition to all the above softwars,  I gust recommend "ILWIS for windows" which is one of the most useful and Applicable; in the spatial data analysis. it is a package that can be used by Free "R" statistical program in developing steps.

Software is an adjective,  not a noun, so it can't be plural, Please?

I suggest the software GeoDa, mainly for geospatial analysis and spatial econometrics.

See the Center for Spatial Data Science (CSDS) - University of Chicago: http://spatial.uchicago.edu/.

Best.

 QGIS IS VERY SIMPLE AND EASY TO USE.

FOR ADVANCED WORKS YOU CAN USE GRASS-GIS. FOR STATISTICS YOU CAN USE R-SOFTWARE.

Dear Mudavath,

Thank you to Bharath Setturu for the articles sharing, interresting aspects ans methodologies.

To complete my answer :

All the free GIS an other software spatial treatment list :

https://fr.wikipedia.org/wiki/Liste_des_logiciels_SIG

By experience, to complete my first answer :

You can use for free web mapping and Web GIS :

1) Umap : simply for using (depending if you want  secure for a sharing map mode, but practical in all case)

2) Gvsig  is the good way for maping and sharing.

https://www.projet-plume.org/fr/fiche/gvsig

http://www.gvsig.com/en

For Gis information adding :

1 ) Mapwindows, a good alternative to Qgis and commercial sofware like Arcgis.

http://www.mapwindow.org/

https://www.projet-plume.org/fiche/mapwindow-logiciel-sig-bureautique-libre

2) Openjump : http://openjump.org/

https://www.projet-plume.org/fiche/openjump

3) PosgreSQL and PostGIS free software): that not the beginner, but this combinaison in vector and raster mode are very powerfull.

TdhGIS (http://www.tdhgis.com) is totally free spatial analysis software. Users can be accomplishing useful work within minutes on virtually any hardware running MS Windows or Linux. TdhGIS focuses on spatial analysis functionality and data exchange with 3rd party software.

Since TdhGIS shares much code with TdhCAD, it provides much CAD like functionality for graphical manipulation of geometric data, exchanges geometric data with TdhCAD and allow a CAD overlay for annotations and symbols.

TdhGIS is a great tool for users who need basic spatial analysis functionality without all the baggage of commercial GIS software.

Spatial Efficiency metric (SPAEF) is proven to be robust when comparing two raster maps. Python and Matlab codes are available at: http://space.geus.dk/tools_products/index.html

Two papers on the metric:

https://www.geosci-model-dev-discuss.net/gmd-2017-238/

SAM - Spatial Analysis in Macroecology software and saga gis are good software for spatial analysis.both software are free.

GeoDa and SAM are free sources and I have been using both. GeoDa is good for maps.

R is also an effective tool for spatial analysis. It is flexible and absolutely free.

Go for; QGIS, GRASS-GIS or ArcGIS Online

Hier, tous Can also test SagaGis ans postGi but if this software are powerfull, they are notre east tout use.

Sincèrement

HP

There are many like below. You can use anyone:

QGIS (http://www.qgis.org/zh_CN/site/) which the most commonly used free open source software for analysis and visualization of spatial data.

ArcGIS Online - the free Developer plan.  https://developers.arcgis.com/plans/

R software. https://cran.r-project.org/web/views/Spatial.htmlhttp://gis.stackexchange.com/questions/45327/tutorials-to-handle-spatial-data-in-r

GRASS-GIS and so on

For doing spatial pattern analysis, you can use FRAGSTATS software (open source) which is designed to compute a wide variety of landscape metrics for categorical map patterns. It is available at: https://www.umass.edu/landeco/research/fragstats/fragstats.html

McGarigal, K., SA Cushman, and E Ene. 2012. FRAGSTATS v4: Spatial Pattern Analysis Program for Categorical and Continuous Maps. Computer software program produced by the authors at the University of Massachusetts, Amherst. Available at the following web site: http://www.umass.edu/landeco/research/fragstats/fragstats.html

Cheers!

QGIS

SAGA GIS

GRASS GIS

QGIS and GRASS if you come from the GIS world and you want to produce nice looking maps.

SAGA GIS if you come from the soils/terrain analysis world, and you want to perform analysis that integrates rasters and DEM metrics.

R if you come from the statistics world and you are interested in real stat analysis.

Julia if you come from a computer science background and speed is important for you.

It all dependes on your expertise. R is probably the most flexibility but with the steepest learning curve for a non-statistician, together with Julia.

QGIS for making maps and R for spatial analysis.
