What do you like best?

As a civil engineer my favorite thing about grass is that it is found as a freeware and is quite easy to install and has great support with regards to using it.

For me, grass is a tool that is quite easy to use and does not require a lot off training although some people may argue that the learning curve is quite steep.

As a gis tool it has great features that I use for the analysis and also integrates exceptionally with other analysis tools.

I love also that I can use grass to convert my GPS data to CVS format or shape-files for use in other tools like arcgis.

Overall, grass is a very vital and crucial tool in my line of work. Review collected by and hosted on G2.com.

What do you dislike?

While I mentioned its an easy tool to use the learning curve for most is quite steep and training anyone on its use is not the easiest thing to do.

Also while its a powerful tool it is not as powerful and advanced with regards to geo-database as the arcgis counterpart. Review collected by and hosted on G2.com.

Recommendations to others considering the product:

I would very much recommend grass to anyone who feels they need a gis tool that is not demanding and that is simple to use. Review collected by and hosted on G2.com.

What problems are you solving with the product? What benefits have you realized?

Grass is a great tool for GIS analysis and for planning projects. I love that it works with various file formats and is easy to handle, to implement and to use.

It also integrates and works exceptionally well with other tools and as such it is a very complete and reliable GIS analysis tool. Review collected by and hosted on G2.com.

It has great tools and intuitive features to perform all required analysis and they function incredibly. I also love that that it has plenty of other pluggins that help perform any kind of analysis exhaustively on maps. Review collected by and hosted on G2.com.

What do you dislike?

The learning curve is steep but after learning the tool its very fun to use it.

Grass is also not as advanced and powerful and it also does not store as much data as arcgis. Review collected by and hosted on G2.com.

What problems are you solving with the product? What benefits have you realized?

Grass has been very vital in my GIS learning in the mapping works and geospatial analysis. It is quite versatile and comprehensive with its functions. I would recommend it to anyone thinking of using it. Review collected by and hosted on G2.com.

What do you like best?

I like that it is an open source software that is used for the evaluation and analysis of geospatial data, image processing, production of graphics and maps, spatial modeling and visualization.

is an easy to use program that offers multiple options for the management of geographic information for the planning and execution of projects, plans, and programs.

I like that it contains specialized tools for the production of graphics and maps that facilitate the presentation of results. Review collected by and hosted on G2.com.

What do you dislike?

is a software that does not have the capacity and quality of presentation of the information when compared with argis, I do not like much for the presentation of very important information because the images, maps and graphics are few innovators and creatives, reason that I use it for the planning of specific, temporary and few important projects. Review collected by and hosted on G2.com.

Recommendations to others considering the product:

Work on improving the quality and expecialization of the process of managing geographic data. Review collected by and hosted on G2.com.

What problems are you solving with the product? What benefits have you realized?

for offering the option to be open source software has been an experimental tool in the research processes of the organization solved various problems of expenses. there have been multiple benefits thanks to grass we have been able to identify problems of planning or execution of projects that have resulted in improvements in the performance and value of the organization. Grass I use for the planning of field trips because it allows us to work with maps in a simple way, being an excellent option if we want to make a map quickly.

What do you like best?

This software have every thing you need to edit and analytics geospatial data. What ever you need, you probably find it in this software. I really enjoy fact, than this software is available as a plugin for QGIS. This kind of access make using features very easy to use. GRASS is a stable and professional work environment. Review collected by and hosted on G2.com.

What do you dislike?

Interface can be more readable, but we don't have tragedy.

This is open source which is characteristic, but support in this kind of software isn't the best and this is how it is here. But when you will know all the possibilities you realize this is very good part of software. Review collected by and hosted on G2.com.

Recommendations to others considering the product:

You can use grass package as plugin for QGIS which make easy to integrate this two software and make very complex workflow to create, analysis and read geospatial data. Review collected by and hosted on G2.com.

What problems are you solving with the product? What benefits have you realized?

If you have many data to analysis you can use GRASS to display it in different, more readable form, just like me. Software make easy to get date which is important and reject the part that is currently unnecessary. The GRASS environment allows for hydrological and environmental analysis.

Customer support is not the best, however that is expected as this is an open source platform. Additionally, the user interface can be tricky for first time users. Review collected by and hosted on G2.com.

What problems are you solving with the product? What benefits have you realized?

We are solving for the ability to dig deep into our data to determine geographic anomalies and outliers. As we have a multi-national business, these insights are extremely important to ensure we remain efficient and well-managed.

What do you like best?

I've used Grass on it's own in the past, however I really enjoy the fact that it is available within QGIS within a plugin. This makes using the best features of GRASS easily accessible. Review collected by and hosted on G2.com.

What do you dislike?

Since the software is open source if you have any problems there support isn't the same as if you were paying big bucks for GIS software (esri), however there is plenty of documentation online via forums etc. Review collected by and hosted on G2.com.

Recommendations to others considering the product:

Use the software on it's own to explore all of the features. Depending on the type of work you do, you may be able to get the features you need from the GRASS plugin within QGIS.

Overall it's a great product. Review collected by and hosted on G2.com.

What do you like best?

The best thing with using Grass GIS is the functionality that it offers. As reported on their site, Grass GIS is used for geospatial data management and analysis, image processing, graphics and maps production, spatial modeling, and visualization.

There are a ton of features that can provide solution to most requests a user can have, and are not included by default in other software (at least not for free). From Remote Sensing and Satellite/LiDAR Imagery management to Hydrology/Groundwater/Wildfire modelling, Grass is able to tackle most challenges that it comes up with.

Another great thing is that Grass is, nowadays, a component integrated within QGis, so someone can benefit from all of the Grass tools within QGis, without having to jump from one software to another. Review collected by and hosted on G2.com.

What do you dislike?

The UI/UX is a bit difficult to use for someone who is accustomed in using ArcMap and QGis, as it is a bit more complex.

Additionally, the data management follows a different logic in contrast to ArcMap and QGis: data cannot simply be "added" but imported, which means that they are stored in another (pre-selected by the user) folder, and then exported back when done with the Grass work. This can be a bit time-consuming for a user.

Additionally, Grass GIS covers a broad set of tools, but unfortunately each tool is not going into much depth - there are useful features missing from tools, like Origin ID and Destination ID in network cost isolines. Review collected by and hosted on G2.com.

Recommendations to others considering the product:

Grass GIS is one of the most valuable, free and open source GIS software you can find out there. You can solve very complex problems, without having to pay anything - if you enjoy though, donations should be more than welcome :)

It is certainly a software that every GIS user should have in their toolbox. Review collected by and hosted on G2.com.

What problems are you solving with the product? What benefits have you realized?

The business problems I am solving are around spatial data management (creation, editing), geo-processing data management (buffers, intersections etc.), and spatial analysis (network analysis etc.). The problems I am solving using Grass GIS are mostly around advanced spatial analysis, that cannot be solved using other GIS software. Review collected by and hosted on G2.com.

Runs on Linux (also runs on Windows). Stable and high performance. Innovative modules solving real world problems. Imports/exports all common formats for GIS (raster and vector). Great hydrologic modeling tools. Awesome community of users and developers. 3D rendering of surfaces is a very useful visualization tool. The simulations are amazing: an overland flow simulation and soil erosion/deposition module. Links directly to spatial databases such as PostGIS. Modular software approach.

What do you dislike?

Recently GRASS added a GUI based map plotting program, which helps with the cartography aspect. Review collected by and hosted on G2.com.

Recommendations to others considering the product:

Subscribe to the mailing list and become part of the community.

The learning curve can be steep, however, this is mostly true of all sophisticated software. This is commonly said about GRASS, but in all fairness it seems to come from people (myself included) who already knew commercial GIS. Other similar commercial software would require at least the same amount of time invested from a point of knowing nothing about GIS.

QGIS is a great companion to GRASS GIS. The QGIS community has incorporated GRASS functions as a toolbox. Very cool integration.

Take the time to read the manuals and understand how regions are setup to work with raster data. It's what a large majority of raster analysis questions relate to on the mailing list. Review collected by and hosted on G2.com.

What problems are you solving with the product? What benefits have you realized?

Environmental modeling. Using LiDAR point cloud data, creating high-definition DEMs for terrain analysis and hydrologic analysis. Delineated hundreds of drainage areas and many drainage networks. Applied Strahler ordering to drainage network. Developed innovative approach to map stream banks using LiDAR, DEMs and slope analysis. Modeled water tables in the wet and dry season using LiDAR based DEMs and soil data (depth to water). Created altered DEMs by filling ditches to show restoration of hydrologic flow. Filter LiDAR point clouds to bare earth as input build DEMs. Volumetric cut/fill analysis to guide post land form design. Review collected by and hosted on G2.com.

What do you like best?

I like the scriptability it provides to users in a Linux environment. At the National Weather Service, we used GRASS to map hydrologic, soil, and geologic information to create flash flood risk maps. The connection from GRASS to bash/korn to the R language was smooth and light weight. The open source nature of this program also provides huge opportunities to not only contribute, but reap the benefits of other scientists contributions. Specific to hydrology, a number of people have created some great tools. Review collected by and hosted on G2.com.

What do you dislike?

While powerful and scriptable, it also has a steeper learning curve than, say ArcGIS. ArcGIS has grown into this large industry-standard GIS machine that can do just about anything you want and with a push of a predefine button. GRASS hasn't kept up with the Arc in this regard. Review collected by and hosted on G2.com.

Recommendations to others considering the product:

Make sure you have the technical expertise as this is not as user friendly as some other GIS software. Review collected by and hosted on G2.com.

What problems are you solving with the product? What benefits have you realized?

Business problems include integrating hydrologic output with other open source scriptable software, quickly deploying the software to other users (without the need for licensing and the very expensive costs that ArcMap has), and analyzing data in a variety of formats for use in other software.
