Comparison between map servers (IMS)
Before we talked about a comparison In terms of price, of various map server platforms, this time we will talk about the comparison in functionality. For this we will use as a basis a study by Pau Serra del Pozo, from the Technical Office of Cartography and Local GIS (Diputación de Barcelona) and although the analysis is based only on the tools that are distributed on the market, it can be useful when deciding for spending money. It is necessary to understand that the map service functionality is only understood as reading and arranging GIS data in such a way that a web browser can display it with certain "basic" functionalities. Among these "basic" functionalities we understand: -Visualization, identification, queries and remote connection. -Combination of layers, calculation of routes, editing "redline", printing to scale.
||GeoWeb Publisher (Bentley)
||Geomedia Webmap (Intergraph)
|Access to CAD formats||Does not read native CAD data||Requires ArcMap Server||Just read Microstation Geographics and Oracle Spatial formats||Requires Desing Server, only reads DWF||Read almost all CAD / GIS formats except Mapinfo||Almost any format, but within the DB.|
|Required Clients||No additional component required||Requires a Java plugin||It only requires a free plugin (VPR)||Requires a Java Applet||Requires a proprietary Micrografx Applet||IIS that comes with Windows|
|Lee Oracle Spatial||si||Yes, also SQL Server native 2008||si||si||si||Yes, almost all native.|
|They can be stored in NT and Linux||Yes allow both||Yes allow both||si||si||si||No, only Windows via ASP.|
|Indepence with regard to GIS tool||No.||Requires ArcView as data server||No.||No.||No.||Si|
|They have wizards||si||si||Yes, although it does require programming||If it requires programming||No.||Si|
A choice of which is better, becomes difficult, especially because the document has some time lag, although these are some of the conclusions:
- If you try to avoid the problem of having to install a plug-in, the best option is MapXtreme.
- If it is required to publish CAD or GIS formats subject to constant maintenance, Geomedia Web o ArcIMSAre the best option.
- If you want to show cartography in CAD format, without much advanced functionality, Bentley Geoweb Publisher y MapGuideAre the best alternative.
- If you are looking for solutions compatible with Windows NT and UNIX, the best solutions are MapXtreme y ArcIMS
- If you want simplicity and economy, GIS Manifold
- Of course this is with proprietary software, in opensource MapBender, MapServer, GeoServer or MapGuide OpenSource Solve and in many cases with greater capacity than the solutions paid.
Prices? We talked about them before, Although there was not Geomedia, but there was Cadcorp. It is surprising that almost all of this can be done by open source platforms, yes Those that are not popular, although a cadastre department in a country requires a decision for a market tool, many times for sustainability ... and in others for dark games
