What do you like best?
SAGA is an open source tool, designed to load vector objects or trace points, lines, polygons and manipulate them by simple or complex analysis methods, these can be liquid flow simulations, motivated by rain, ocean currents, evaporation and others. Other models that can be cited as the simulation of particle erosion, maximum entropy, the management of photogrammetric composition of remote sensing images
SAGA includes within its models, the concepts developed by Morgan, Finney, Duzant, Burrough, Hugget, among other professionals dedicated to quantitative geography.
SAGA saves equipment resources focusing its effort on data processing and not on visualization with a high level of aesthetics, allows QGIS to be used as a visualizer of the results of the processes and allows the user the possibility of obtaining a product . Graphic printing of higher quality.
SAGA can be compared with Esri Arc ToolBOX, since it presents the same performance with very similar results.
What do you dislike?
It is a bit cumbersome to show the representations of the obtained processes, the creation of the print design and other attributes of a final map; I think that to have a print quality map, the results are better handled with other compatible software such as QGIS or GVSIG, which have developed more those processes.
I consider that it is necessary to devote a little more to the development of the data loading interface, explanation of the method and other things that contribute to the learning of new users
Recommendations to others considering the product
The users must handle very well the concepts of each one of the methods of analysis of the plot included in the software, which variables should be handled, the projection of spatial data. All this so that they do not present problems with the obtained results or translate bad interpretations of the results.
I carried out several practices with LDD and Pattern Analysis for the identification of land with few threats due to extraordinary events of rain in the city of Barcelona, Venezuela, whose results were satisfactory.
What business problems are you solving with the product? What benefits have you realized?
The greatest contribution that SAGA offers us is the application of complex analysis methods of localized data for free, it facilitates geoscience researchers, who do not have high budgets for their research, operate software with a high level of complexity without cost, The tool is fed with the findings that these scientists can launch in the future and share with the developers to create a new version of an existing or completely new analysis method, in a human environment practically free of cost.
