Hey folks, I just found a cool site which it inform dozens of free GIS data site. check it out here http://freegisdata.rtwilson.com/ Hope this little post useful for you regards :D

ORFEO Toolbox (OTB) is distributed as an open source library of image processing algorithms. OTB is based on the medical image processing library ITK and offers particular functionalities for remote sensing image processing in general and for high spatial resolution images in particular. OTB is distributed under a free software license CeCILL (similar to GPL) to encourage contribution from users and to promote reproducible research. The library is intensively tested on several platforms as Linux, Unix and Windows. Most functionalities are also adapted to process huge images using streaming and multi-threading as often as possible. Among other, OTB provides a number of heavily documented functionalities as image access: optimized read/write access for most of remote sensing image formats, meta-data access, visualization; filtering: blurring, denoising, enhancement; feature extraction: interest points, alignments, lines; image segmentation: region growing, watershed, leve...

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...

Dalam mempelajari fusi citra dan pan-sharpening, banyak dari kita yang merasa kebingungan untuk  memulai. Kebingungan ini dapat berasal dari kurangnya pemahaman akan metode dan algoritma, dasar teori fisis penginderaan jauh, konsep spasial/spectral citra, sampai sarana dan prasarana (software dan data). Untuk yang terakhir ini, saya sungguh sangat mengalaminya ketika kuliah dulu. Bagaimana susahnya memperoleh data yang “layak” untuk digunakan sebagai sarana belajar fusi citra. Ketika sedang mengerjakan skripsi, saya sempat kebingungan untuk mencari citra yang dapat digunakan untuk pemetaan skala 1/50.000. Data yang tersedia di jurusan saya hanya Citra SPOT-5 HRG dengan resolusi spasial 10 meter yang tentunya tidak cukup detil untuk pemetaan skala 1/50.000. Setelah saya pelajari citra tersebut beserta metadatanya dalam format DIMAP, akhirnya saya mengetahui kalo citra SPOT tersebut terdiri dari 2 dataset, yaitu dataset multispektral dengan resolusi 10 meter dan dataset Pankromatik denga...

HighView is an advanced image fusion and pan-sharpening software program. It uses GeoSage's state-of-the-art and highly efficient image fusion algorithms that have been developed over the past few years and successfully merges low-resolution multispectral bands with high-resolution panchromatic band of recent satellite images (e.g., GeoEye-1, QuickBird, IKONOS, KOMPSAT-2, FORMOSAT-2, ALOS, SPOT-5 and Landsat 7 ETM+). Highlights: 􀂙 Band combination and image stretching 􀂾 A hybrid of both linear and nonlinear image stretching 􀂾 Stretched output imagery in 24-bit BMP and/or un-stretched output in GeoTIFF format 􀂾 A GUI-based batch processing function able to process hundreds or thousands of images overnight. 􀂾 Advanced simulation method for making true-colour composite from SPOT-5 false-colour Near Infrared/Red/Green input or any other colour infrared (CIR) imagery. Six methods or colour templates are provided. (Only included in HighView Professional Version 2.5) 􀂙 Pan-sharpenin...

adalah sebuah algorithm image fusion/pan-sharpening berbasis operasi aritmatika/map algebra, namun menggunakan prinsip fisis perjalanan gelombang elektromagnetik dalam penginderaan jauh. Tidak seperti algoritma aritmatik lain seperti brovey yang menginjeksikan detil pankromatik melalui operasi multiplikasi yang pada akhirnya mengacaukan komposisi spektral citra multispektral, SFIM mengambil detil pankromatik tanpa menyentuh atribut spektral dari citra multispektral. Sehingga, nilai spektral dari citra multispektral tidak terdistorsi/teralterasi. Tidak juga seperti algoritma berbasis transformasi seperti PCA sharpening atau IHS transform, SFIM tidak mengambil informasi intensitas, sehingga dia tidak tergantung pada julat spectral dari citra pankromatik, sehingga dapat digunakan untuk memfusikan saluran SWIR pada citra ASTER atau LANDSAT tanpa perlu khawatir informasi spektral teralterasi/terdistorsi terlalu jauh, walaupun tidak ada citra pankromatik yang direkam sampai spektrum SWIR. Al...
