How to convert multiple GIS Layers (in shapefile or other GIS formats) to Single DXF CAD file. This workflow can be done in QGIS A free Geographic Information System Software, and may be useful for certain data management workflow or GIS-CAD Integration.

How to convert BIM Files in Revit RVT or IFC format to geospatial GIS Format such as Shapefile or Geodatabase using ArcGIS Pro Software.

Definisi Sistem Informasi Geografis Sistem Informasi Geografis (Geographic Information System/GIS) yang selanjutnya akan disebut SIG merupakan sistem informasi berbasis komputer yang digunakan untuk mengolah dan menyimpan data atau informasi geografis (Aronoff, 1989). Secara umum pengertian SIG sebagai berikut: ” Suatu komponen yang terdiri dari perangkat keras, perangkat lunak, data geografis dan sumberdaya manusia yang bekerja bersama secara efektif untuk memasukan, menyimpan, memperbaiki, memperbaharui, mengelola, memanipulasi, mengintegrasikan, menganalisa dan menampilkan data dalam suatu informasi berbasis geografis ”. Data Spasial Sebagian besar data yang akan ditangani dalam SIG merupakan data spasial yaitu sebuah data yang berorientasi geografis, memiliki sistem koordinat tertentu sebagai dasar referensinya dan mempunyai dua bagian penting yang membuatnya berbeda dari data lain, yaitu informasi lokasi (spasial) dan informasi deskriptif (attribute) yang dijelaskan berikut ini : ...

Climate Hazards Group InfraRed Precipitation with Station data (CHIRPS) is a 35+ year quasi-global rainfall data set. Spanning 50°S-50°N (and all longitudes) and ranging from 1981 to near-present, CHIRPS incorporates our in-house climatology, CHPclim, 0.05° resolution satellite imagery, and in-situ station data to create gridded rainfall time series for trend analysis and seasonal drought monitoring.  

Current imaging technologies are so advanced that photography today is not only about the photo result, but also many additional properties, include the photo location. Embedding location is very common today because almost all imaging enabled devices (smartphone, notebook, tablet, GPS handheld, etc) as abilities to store GPS coordinates into the EXIF metadata inside a photo. Online services like FLICKR or Google Maps also provide ability to host a collection of photos/images that also can display the photos based on its coordinates into an online maps.  Now for GIS users, does the display photos or images based on its location into a GIS software?. The answer is yes you absolutely can. You can do this kind of visualization almost in every GIS software available on the market. ArcGIS and QGIS absolutely can do this. Now if you are interested to do this in GIS environment, I have created a video tutorial about how to do it in ArcGIS below. 

CAD and GIS are both technology related to mapping and spatial dimensions of earth surface objects. CAD mainly is used in the Architecture or civil engineering domain (microscale) and GIS is used for spatial analysis at the landscape/regional level. Both of the technology are using spatial representation in vector graphics structures. The format for these vector data is various, but DWG is a major format in CAD since decades ago, and Shapefile/SHP is the major and most used spatial data format in GIS for at least since the nineties.  Because both of them are using vector graphics, straight conversion between two mainstream formats is absolutely possible. Modern CAD software mostly supports direct reading of SHP format and vice versa. CAD also has point representation, polyline representation, and polygon representation as well as Shapefile GIS format. There are no many differences between those two formats. The only difference is CAD DWG format usually didn't store tabular informat...

My two previous posts concerned about tile layers served as basemap in raster format. Tile layer in raster format is superb because it is deliver fast reading, great compatibility between systems and standards, Tile layer in raster format is also works for any kind of data and independent from the source data format. Either you have thematic maps in vector format or satellite imagery/DEM in raster format, Tile layer in raster could handle them well. But technology always changing. In recent years, development of tile layer in vector format got its fruition. It is somewhat better than raster, but it is not dedicated to replace the raster based tiles. It has specific function which is mainly to serve basemap in VECTOR format. By using vector format, you can get : 1. Smaller file size to serve, so higher performance is guaranteed. 2. Dynamic and good resolution/display in every scale or zoom level (vector ftw man). 3. Faster generation and processing time compared to raster. 4. No...

Saya baru mempublish salah satu kumpulan tutorial (lama tapi) baru tentang pengolahan gps di dalam GIS di GPlay Books, dengan harga yang (semoga) cukup murah, Hasil penjualan insya Allah sebagian besar digunakan untuk membeli kopi agar otak bisa memproduksi buku2 tutorial lain di masa mendatang, Terimakasih, Link Buku di Google Play Books di sini https://play.google.com/store/books/details?id=wILvDAAAQBAJ

Import data spasial format shapefile ke dalam DBMS PostgreSQL selain dari client software seperti qgis dan arcgis, dapat juga dilakukan menggunakan PGAdmin 1. Install PostgreSQL 2. Install PostGIS via Application Stack Builder 3. Buka PGAdmin, koneksikan ke database Postgre 4. Dari Menu PGAdmin, klik menu Plugins>PostGIS Shapefile and DBF loader 5. Import 6. Test Koneksi dan display data dari client (ArcGIS atau QGIS), atau Web Based Client apabila ada. Thats it
