geoCMS

Just a couple of videos featuring our new geoCMS platform released a couple of months ago. This is a web GIS based application designed to easily create, manage and publish spatial data.

Currently there are three modules available: geooportal, geoCMS and a mobile application. The first two work together as a spatial data publishing tool. One can create and manage vector layers, layer groups and maps along with the tools that are available for each map. The standard WMS or XYZ raster data sources can also be easily consumed by the geoportal.

The mobile application is used for outdoor data collection - it is also a map centric app that drastically improves the efficiency of the outdoor data collection and managment process.

All modules exchange data in real time. When there is no Internet access, the mobile device stores the data localy and then synchronises it with the database as needed.

A live example may be found here: http://cyklisci.maphive.co/. This is an application powered by our platform - this particular one focuses on hGIS, old maps and such.

Another example: http://cyklisci.maphive.co/. This one focusing on collecting data from geoportal users.

OpenLayers.Layer.Panoramio

While working on one of our recent projects we came with an idea (or I should rather say - we eventually managed to spare some time on something not strictly project related ;) that giving some more context to a map should improve the perception of the map data itself:

Export all components of given type from manifold map file

You may sometime need to export all the components of given type so they can be used in another GIS environment. Here goes a script that does exactly this. The example exports all the drawings and tables to either shp or xls:

using Manifold.Interop.Scripts;
using M = Manifold.Interop;

class Script {
	static void Main() {
		//Some setup stuff first
        string exportFld = "H:\\ExportedComponents\\";

        M.Application mApp = Context.Application;
        M.Document mDoc = (M.Document)mApp.ActiveDocument;
        M.ComponentSet mCompSet = mDoc.ComponentSet;

        //Exporters
        M.ExportShp shpExporter = (M.ExportShp)mApp.NewExport("SHP");
        shpExporter.ConvertPolicy = M.ConvertPolicy.ConvertAll;

        M.ExportXls xlsExporter = (M.ExportXls)mApp.NewExport("XLS");
        xlsExporter.ConvertPolicy = M.ConvertPolicy.ConvertAll;

       //iterate through all components
        for (int i = 0; i < mCompSet.Count; i++ )
        {
            mApp.StatusText = "Reading component " + i.ToString() + " of " + mCompSet.Count;

            switch (mCompSet[i].Type)
            {
                case M.ComponentType.ComponentDrawing:

                    shpExporter.Export(mCompSet[i], exportFld + mCompSet[i].Name + shpExporter.DefaultExtension, M.ConvertPrompt.PromptNone);

                    break;

                case M.ComponentType.ComponentTable:

                    xlsExporter.Export(mCompSet[i], exportFld + mCompSet[i].Name + xlsExporter.DefaultExtension, M.ConvertPrompt.PromptNone);
                    break;
            }
        }

        mApp.StatusText = "";
        mApp.MessageBox("Done!", "Info");
	}
}

Upload and save image in a database - ExtJs and ASP.NET

It's been a while since the last post appeared here so this one will be rather longish ;-)

Recently in one of our projects we had a requirement to allow users to upload their images to the database so they can later be viewed by other users of the application.

For the clientside we used the ExtJs framework while the serverside was ASP.NET and c#.

Basically the process can be divided into three parts: image upload on the clientside, image processing on the server side and also image retrieval from the database so it can be displayed again in a browser.
