Today we live interesting scenes, in which free software and privative coexist contributing to the industry in conditions of increasingly more balanced competitiveness. Perhaps the geospatial issue is one of the fields in which open source solutions are as robust as non-free license solutions; nevertheless, before these two extremes a market arises for those who do not want to leave for the open, but who can not pay the costs of the popularized privative. This is low cost software.
I have always been struck by these solutions, because in a curious way, they have an interesting niche. Of those that I liked the most was Manifold GIS, today I have taken a look at Simple GIS Software, an application that has many features that are interesting to know and evaluate.
How simple is Simple GIS Software
Simple GIS Software (SGS) provides a work response from two fronts, not only the conventional desktop, but the collaborative, through a server that can also provide WMS (OGC Standard) services. The latter is interesting, since SGS provides the capabilities to capture, store, manipulate, analyze and present spatial and geographic data; combining capabilities and the power of a traditional database.
The proposal of SGS is to be an easy-to-use software, with a short learning curve and the simplicity of doing GIS with a solution that costs only 25 dollars. Much of what Simple GIS Software does is very similar to what other free and proprietary tools do; maybe the interesting thing about this solution is its practicality, in doing in a simple way what most requires a user, without complications of multiple buttons and plugins. Simple GIS Software not only produces and presents maps, it counts (and this seems quite intuitive) with analytical capabilities to help solve real-world problems based on spatial relationships between objects.
I have downloaded the trial version, and I have tried to download the entire OSTA data layer from UTAH. It has been processing a few minutes 10, which has been delayed more is the layer of streets, but because I have requested that according to geocode. It seems to me an impressive thing, that I would like you to make other applications, because in the end the whole base of this state has been lowered, it has made functions of topological construction and dissolution for the conversion of data to shp layers. With some VBA editing my friend «Filibuster»Has made adjustments to download the entire Open Street Map base in Bogotá and ... as our friend, Bombazo!
Like it shows, From here you can download the shp layers of Open Street Map of Bogotá, between the coordinates -74.343, 4.536; -73.903,4.813.
Honestly it's worth the half hour I've spent.
It has quite simplicity in the analysis of filtered searches, for geomarketing type applications. The capacity of the so-called 'proximity analysis' of this software can be very well taken advantage of by an infrastructure company that carries out studies to build roads in order to determine possible areas impacted. You can integrate GPS data to display location information in real time or provide routing and navigation information from the software.
The layout of maps is quite acceptable, practical, thought of what is ultimately sought to convey ideas.
Simple GIS Client - Desktop GIS Software
Supports vector data of type Shapefiles, Simple GIS Graphic Layers, DXF, Simple GIS Server Vector, Event Layers with spreadsheets and any database via ODBC connector. The CAD type edition is quite practical, in common commands such as offset, trim, fillet, split, with efficiency in adding or removing vertices, undo / redo that does not kill the memory, despite doing heavy tasks, cogo support for courses and distances, and a functional snap. In summary, sufficient editing capacity.
From the surprising, edition of shape files in multiuser mode. Considering that this is an archaic file with the limitations of its just 16 bits, which came to us as a de facto standard and from which it has been so difficult to undo after more than 20 years.
In terms of raster support, it includes BMP, Jpeg, Tiff, Jpeg 2000, MrSid, Simple GIS MRI (multi resolution image), Simple GIS Server Image Layers, WMS and recently includes WMS tessellation (WMTS)
The simple GIS client works on Microsoft Windows. It has the power, lightness and functionality to work as a desktop GIS software application. If you want to use it for field or navigation, you can run on a tablet that supports windows. It makes common functions of thematic maps, selection sets, filtering, spatial and attribute queries, editing and viewing of .shp files in multiuser mode, it has advanced editing functions, map production, geocoding, routing, among others. I find impressive ability to download a whole set of Data from Open Street Map, for example an entire state of the United States, with geocoding with the state or with Zipcode.
You can create detailed geocoded and fully routable street maps using only a few clicks. It also contains many tools for geoprocessing images of interesting scope, being able to customize the software using Visual Basic for Applications (VBA).
It produces outputs of acceptable quality that can be printed directly or exposed in common graphic formats in order to be able to be inserted into other software packages.
Simple GIS Server - Mapping GIS Software
Given the need to share GIS data through a network, local, broadband or Internet, Simple GIS Server is a Microsoft Windows server that uses TCP / IP and contains a standalone Web server that can serve vector and / or rasterized data to GIS clients through data networks or provide open geospatial web mapping services (WMS). The new version of Server allows you to take maps created in Simple GIS client and publish them as a WMS in a very simple way.
It is possible to serve data and configure SSL authentication. It is also possible to connect it to AVL (Automated Vehicle Location) through a plugin for remote control via GPS.
In conclusion, Simple GIS Software, despite being a tool with guidance to North American users, has an interesting potential as a low-cost solution. For 25 dollars I expected less; in my opinion it is a software with client-server capabilities, with sufficient capabilities
Time will tell how far it evolves.
