LINK FLORESTAL - FOREST GIS GIS, Maps, and Cartography at › GIS Lounge Multicriteria analysis to study erosion risk using ArcGIS Today we are going to study the erosion risk of a terrain. With multicriteria analysis we are going to analyse the slope as well as its proximity to rivers. We will follow these 3 steps: 1. 2. 3. 1. We need a DTM raster layer. First of all we are going to use the Slope tool: Spatial Analyst Tools > Surface > Slope Now, the problem is that we have data in a different scale. Therefore we will reclassify it in 4 degrees according to its gradient, being the highest number the one of biggest inclination. Spatial Analyst Tools > Reclass > Reclassify First, click Classify in order to fix the classes and define the break values. Click OK and you return to the previous window where we will value the areas with highest inclination with a bigger number. 2. We need to obtain the river basins. Spatial Analyst Tools > Hidrology > Flow accumulation Next, with the generated raster we select: TRICK: Going back to classify inside reclassify, we can observe the graphic and find the accumulation value of the river.

Download Free RADARSAT Data of Canada - GIS Resources Canada’s RADARSAT-1 is a radar satellite and was launched in November 1995. It carries a Synthetic Aperture Radar (SAR), it acquired images of the Earth day or night, in all weather and through cloud cover, smoke and haze. RADARSAT-1 was a Canadian-led project involving the Canadian federal government, the Canadian provinces, the United States, and the private sector. It provided useful information to both commercial and scientific users in such fields as disaster management, interferometry, agriculture, cartography, hydrology, forestry, oceanography, ice studies and coastal monitoring. RADARSAT orthorectified mosaic image of Canada The Government of Canada provides free access to RADARSAT through the website “Natural Resources Canada”. The ortho-rectified mosaic of Canada RADARSAT data is available via FTP (file transfer protocol) server of Natural Resources Canada. Download Data from FTP Server: RADARSAT orthorectified mosaic data of Canadian province (100m).
OpenEV Home Conservação da Biodiversidade com SIG - Meio Ambiente - Oficina de Textos Projetos de conservação da biodiversidade e desenvolvimento sustentável, como o planejamento espacial de áreas protegidas, modelagens de alterações no uso e na cobertura do solo, e o desenvolvimento de planos de manejo para espécies ameaçadas apóiam-se em Sistemas de Informações Geográficas (SIG). Conservação da biodiversidade com SIG vem atender à demanda de usuários de SIG envolvidos nesses projetos, além de preencher a lacuna entre pesquisa e aplicação prática na área.
Maptitude Geographic Information System and mapping software Mapping made easy Answer a few simple questions and Create-a-Map Wizard™ makes a map at any scale, from all of the countries of the world, to streets around an address, landmark, or intersection. With a few clicks of the mouse, MapWizard® automatic mapping technology helps you create color and pattern maps, dot-density maps, scaled-symbol maps, and maps with integrated pie or bar charts. You can customize the colors, styles, and labels in your map. Once you understand the patterns hidden in the numbers, share your maps to tell your stories. Copy them to reports and slideshow presentations, save them to JPEG, PNG or HTML for use on websites, or print them out as handouts or wall-size posters. Maptitude mapping software is only US$695 and includes a FREE country package ($595 value) that includes an up-to-date street layer with addresses for pin-mapping (geocoding) and travel time information for computing routes and drive-time rings.
The Advantages of a UAV - LiDAR News Mobile laser scanning and airborne laser scanning point clouds come with their unique advantages and disadvantages. Mobile laser scanners cannot acquire data from building rooftops and the airborne laser scanners cannot acquire data from building facades because of their view angles. Therefore the point cloud measurements from any of these two scanners have areas which do not have enough points to represent the 3D structures properly. One solution to increase the density of point clouds is to use UAV cameras. Tony Nedkov has used a UAV camera in order to generate point cloud of a specific building. To do so, Tony has applied Structure from Motion (SfM) techniques to the acquired video. Primary steps of his work can be seen in the following images and in the video provided with the link below.
