Free Remote Sensing Software :OPTICKS 4.10.0

Opticks is an expandable remote sensing and imagery analysis software platform that is free and open source. If you are interested you can learn about the history of Opticks.

If you've used commercial tools like: ERDAS IMAGINE, RemoteView, ENVI, or SOCET GXP, then you need to give Opticks a try. Unlike other competing tools, you can add capability to Opticks by creating an extension. Opticks provides the most advanced extension capability of any other remote sensing tool on the market.

Feature:

• Free and open source
• Supports the following file formats: NITF 2.0/2.1, GeoTIFF, ENVI, ASPAM/PAR, CGM, DTED, Generic RAW, ESRI Shapefile, HDF5, AVI, MPEG, JPEG, GIF, PNG, BMP
• Zoom, pan, rotate spatially large datasets
• Quickly layer GIS features, annotations, results, and other information over your data to provide context
• Many image display controls such as colormap, histogram, transparency, etc.
• Support for datasets larger than four gigabytes
• Analysts can quickly combine steps using graphical wizards
• Support for processing data in its native interleave of BIP, BSQ or BIL
• Get extensions to drop in new capability.

Geographic Translator : MSP Geotrans 3.2

Geotrans 3.2 has been released. Geotrans is the coordinate conversion application or a geographic translator program among a wide variety of coordinate systems, map projections, and datums. Geotrans runs in Microsoft Windows, LINUX and UNIX environments. GEOTRANS can also be used to convert large numbers of coordinates contained in either text files (.txt) or comma separated values (.csv).

To convert a set of coordinates, simply select the coordinate system or map projection, the datum, in which your coordinates are defined, then enter the source coordinates, select the coordinate system or map projection, and the datum, to which you want the coordinates to be converted, and click on the Convert button. The resulting coordinates will be displayed.

AutoDEM (create DEM from scanned topographic maps)

AutoDEM (aka as AutoMNT) is a freeware GIS software to create Digital Elevation Models (DEM) from scanned topographic maps for Windows.
Through different data layers (map, contours, DEM, etc.), AutoDEM provides many tools for :

    Topographic map analysis
    Contour lines extraction and reconstruction
    Contours to DEM interpolation and DEM analysis
    DEM to TIN conversion
    Toponyms extraction

Most of the worldwide file formats used in the GIS community are supported. AutoDEM can also directly import data from web servers (TerraServer, WebMapService, WFS, …) 

What AutoDEM can do
Here are most relevant features of the software :

    Multi-layers interface to manage original map, extracted contours, elevation grid and triangular mesh.
    Common classical image editing tools (zoom, hand, selection, pen, eraser, lines etc.)
    Support every common image file formats supported by GDAL (JPEG, PNG, PGM, PNM, BMP, GIF …). Complete list
    Support most DEM file formats supported by GDAL. Complete list
    Plug-in based architecture through a DLL mechanism (a Development Kit is coming)
    Contour lines extraction from map through different filters
    Contour lines reconstruction and edition
    Tools to semi-auto set contour lines' elevations
    Contour lines interpolation with different methods like geodesic distances, Partial Differential Equations, Inverse Distance Weighted Averaging, Radial Basis Functions and kriging
    Elevations related tools
    Embossing filter to preview the terrain rendering
    Realtime 3D visualization and navigation with the Level of Detail (LOD) Duchaineau's `Realtime Optimally-Adapting Meshes' (ROAM) algorithm included (need an OpenGL graphic card)
    DEM to regular or irregular (TIN) mesh generation and export
    Import maps and DEM from WebMapFeature (WMS) or TerraServer
    Lot of other features…

As AutoDEM is still a research tool, it's updated very soon and will be developped for many years, and you are encouraged to ask us the improvements you would like to see and help us to make AutoDEM an easy-to-use and powerful tool.

Network Analyst : Route Optimization

The Route solver is the best way to optimize a given circuit so we can find the best path between any number of stops and. Let’s pretend we are tourists who want to see some interesting sites in a city and need some help planning our day so we’ll spend the least amount of time driving.

Step1:

-       Open ArcMap and add  the network dataset

-       Check on the Network Analyst toolbar, and then select New Route from the drop down menu. Also, click the button right next to the drop down menu to show the Network Analyst Window.

Step2:

-Right now we need to load the stops we can create them manually by activating the Create Network Location Tool and clicking on the screen while your pointer is in the flag with crosshairs shape. Or, we can load them from another layer

Step3:

 Now click the Solve button and  everything is  ok !
