Pembuatan Peta Bayangan Gunung (hillshade) dari DEM dapat dikategorikan dalam dua metode, yaitu manual dan analytical. Manual shading berarti melakukan proses shading secara manual ............ Sedangkan analytical hillshading berarti.... [gambar contoh hillshading manual dan analytical] Khusus untuk analytical hillshading, beberapa algoritma telah dikembangkan. Satu yang paling umum adalah algoritma.. yang diimplementasikan dalam kebanyakan perangkat lunak RS/GIS. Teknik - teknik yang lain, sebagian besar merupakan pengembangan dari teknik yang sudah ada. Teknik ...., misalnya, telah dikembangkan lebih lanjut menjadi beberapa varian seperti Swiss hillshading method dan MDOW hillshading. Masing - masing  algoritma memberikan hasil hillshading yang berbeda

I just found a simple way to add google images into ArcMap Project after exploring some RS/GIS forums. As we already know, since ArcGIS 9.2 we can access tiled services of basemaps from ESRI. This new feature permitted us to use worldwide detailed maps or high resolution imagery as our base map,data source or simply just background information of our mapping project. Then, We may further asking, could popular map/imagery service provider like google or microsoft also be added into ArcMap?. The answer is yes. codeplex has developed an ArcGIS extension called ArcBrutile , which it main goal is enabling tiled map/imagery services can be added into ArcMap. The extension can make WMS/WMS-C map services, Microsoft Bing and Google Images/Maps added into ArcMap view. Below is example of my experiment: Download the needed software from this forum . Enjoy!!

Here is short tip to create automoved graphics or labels like annotation does in ArcMap. Normal graphics will not moved when we are trying to zoom or pan the data view in Layout mode. Sometimes it can bring serious problems when we are creating multi sheet or multi scale map. We can use manual way to move graphics (aargh, its time consuming), using annotation or converting graphics into shapes in order to make auto movable graphics/text. But trust me, that would not efficient if you re actually don't need annotation or additional meaningless data. better save your HD space folks!. Ok here are the tip sequences, 1. when you re in layout mode, activate the layout toolbar, 2. search "focus data frame" button, click it, 3. then create your text or graphic using drawing toolbar, 4. After it is done, try to pan or zoom the data view,the created graphics will automatically moved according to the panning/zooming direction (in this example image, the map moved to the down directio

Chips, the Copenhagen Image Processing System, is a general-purpose software package for remote sensing image processing and spatial data analysis with extensive support for NOAA AVHRR data.
