River Streams Order Network Mapping (Strahler, Shreve, Horton) in QGIS Based on Vector Topology (No DEM needed)

Image
How to perform river / streams network order mapping in QGIS using vector topology approach. Order calculation directly computed from the polylines topology so you don't needs river networks extracted from DEM for this to works. The result will also be more consistent with the field situation because you can use river / stream polyline data from the topographic maps or digitized maps.

Online Raster and Vector Basemap Comparison in QGIS and Which Is Better for A Mapping Project

Image
There are two types of basemaps. Raster tile basemap and vector tile basemap. The raster tile basemap is pre-rendered, stored on the server, and displayed unchanged by the client. The World Imagery basemap is a good example of a raster tile basemap and an example of a basemap that cannot be displayed as a vector tile basemap. The Vector Tile Basemap references a set of web-accessible vector tile data (points, lines, and polygons) and the appropriate style for drawing those tiles. Vector tile basemaps are used for non-image content. Vector tile layers can be adapted to the resolution of your display device and can be redesigned for multiple uses. Vector tile basemap technology now is supported in latest GIS Software such as ArcGIS Pro and QGIS. There are few vector tile format that have been developed by various company or agency. For example, Mapbox have developed MBtiles and MVT as Vector Tile format, ESRI and Google use Protocol Buffer Format (PBF) for its vector t...

Download Soil Moisture Raster Data Directly in QGIS

Image
Soil moisture plays an important role in agricultural monitoring, drought and flood prediction, forest fire prediction, water supply management, and other natural resource-related activities. Soil moisture observations can warn of imminent drought and flood conditions before other  standard indicators are triggered.   As defined in AMS Glossary of Meteorology, soil moisture is "the total amount of  water vapor-containing water in  unsaturated soil." Soil moisture (sometimes called soil water) refers to surface water  in the pores of the soil, not rivers, lakes, or groundwater. Soil moisture levels are determined by a variety of factors other than weather conditions, such as soil type and associated vegetation. Second, soil moisture affects the various dynamics of soil and plants. Surface soil moisture is  water located 10 cm above the soil, and root zone soil moisture is  water  available to plants-generally considered to be located 200 cm ab...

Download Digital Elevation Model Data From ALOS PRISM Directly In QGIS (100% Free!!)

Image
ALOS-1 (also known as Daichi) was launched on January 24, 2006 and completed its operational phase on  May 12, 2011, after a successful five-year acquisition worldwide. ALOS was one of the world's largest earth observation satellites tasked with collecting high-resolution land observation data on a global scale. The satellite consists of three instruments: an altitude visible and near infrared radiation meter (AVNIR-2) for accurate observation of land cover, and an L-band synthetic aperture radar (PALSAR) phased array type for day and night and all weather conditions. Was installed. Panchromatic remote sensing device (PRISM) for stereo mapping.   The purpose of its mission was to provide the user community with enough data to create a map at a scale of 1: 25,000. Development of digital elevation models and related geographic data products. Conduct community observations to support the Sustainable Development Goals. Natural resource research; development of sensor and sate...

Spatial Density Analysis in QGIS

Image
Density analysis captures known quantities of phenomena and distributes them throughout the landscape based on the spatial relationship between the measured quantity  at each location and the location of the measured quantity.  Density analysis captures known quantities of phenomena and distributes them throughout the landscape based on the spatial relationship between the measured quantity  at each location and the location of the measured quantity. The    Density tool spreads a measured amount of  input point layers over the landscape to create a continuous surface. As an example  of a   density analysis application, consider a retail  chain with multiple stores in a particular area. For each store, management has sales from customers. Management believes that customers choose one store over another based on distance traveled. In this example, it is natural to assume that each customer  always chooses the nearest store. The farthe...

Access and Downloads Historical Satellite Imagery in ArcGIS Pro. Part 1

Image
This video tutorial is about how to directly viewing and downloading historical satellite imagery in ArcGIS Pro. ArcGIS Pro must be connected to the internet and you must have access to ESRI Living Atlas for this method to works. Access to ESRI Living Atlas could be obtained by purchasing and subscribing ArcGIS Online organizational account, apply for a 21 days ArcGIS free trial, or apply for ArcGIS Learn program. You can also get a limited time ArcGIS online and Living Atlas access by participating in ESRI MOOC available from esri.com/training.  Using this way, you can view, analyze and download few kinds of satellite imagery sensors available on the market. For example, Landsat-8, Landsat-9. MODIS, Sentinel-2, Sentinel-1, and many others. Some of the URL endpoint you can use as starting point are here.  LANDSAT-8 SENTINEL-2 So far, this is the easiest method to obtain direct access to historical satellite imagery. There are also limitation about this service. One of them is ...

Analisis Kebakaran Hutan (Forest Fire) Menggunakan Normalized Burn Ratio (NBR) Dari Citra Satelit

Image
Berbagai macam teknik pemetaan telah dikembangkan dalam mendukung upaya - upaya pencegahan kebakaran hutan di seluruh dunia. Salah satu teknologi pemetaan yang banyak digunakan dalam penanganan kebakaran hutan adalah penggunaaan citra satelit penginderaan jauh.  Normalized Burn Ratio (NBR) Salah satu teknik analisis yang telah dikembangkan dan banyak digunakan adalah teknik Normalized Burn Ratio (NBR) yang diturunkan dari sensor - sensor penginderaan jauh satelit yang memiliki kepekaan spektral hingga spektrum inframerah gelombang pendek ( Short Wave Infra Red ). Contoh-contoh sensor yang dapat menerapkan NBR antara lain Landsat 4 sampai Landsat 9, ASTER, SPOT 5 hingga SPOT 7, Sentinel-2, MODIS, dan berbagai sensor lainnya.  Contoh Hasil Analisis NBR Rumus perhitungan NBR ( mirip dengan NDVI, bedanya hanya saluran yang digunakan ) adalah sebagai berikut: Untuk citra Landsat 8 dan Landsat 9, penerapan NBR berarti menggunakan saluran 5 dan Saluran 7.  Nilai output NBR miri...

All About Landsat-9 Satellite Imagery

Image
Landsat 9 berhasil diluncurkan pada Senin, 27 September 2021 dari Vandenberg Space Force Base di California. Landsat 9 Merekam permukaan bumi selebar 185 kilometer. Resolusi spasial untuk citra multispektral sebesar 30 meter, atau seukuran lapangan bisbol. Untuk band pankromatik resolusi spasialnya sebesar 15 meter. Data Landsat 9 tersedia untuk umum dari USGS, dan dapat diunduh secara bebas, misalnya dari portal EarthExplorer  atau GLOVIS .  Landsat 9 sesuai namanya, merupakan satelit Landsat generasi ke-9 dimana sebelumnya telah diluncurkan Landsat 1 sampai Landsat 8. Secara spesifikasi, Landsat 9 relatif mirip dengan Landsat 8, baik dari sisi sistem maupun jenis data yang dihasilkan.  Landsat Satellite Family (Image Courtesy USGS) Instrumen Landsat-9 terdiri dari Sensor OLI-2 (Operational Land Imager) yang merupakan penerus sensor OLI-1 yang terpasang pada Satelit Landsat-8, dan Sensor TIRS-2 yang merupakan penerus Sensor TIRS-1 yang terpasang pada Landsat-8.  Sen...

Landsat-9 in ArcGIS Pro (NDVI and Pan-Sharpening Analysis)

Image
Adding, Displaying, Manipulating, Processing and Analyzing Landsat-9 Data in ArcGIS Pro. For example, Pan Sharpening and NDVI Analysis. Due to Landsat-9 MTL Metadata is not yet supported in ArcGIS Pro 2.9.2 when this video is published, some of the automatic tasks that can be done easily with Landsat-8 can't be done in similar ways with Landsat-9. So we must be patient until the day is come. But on the other hands, all the raster functions implemented in ArcGIS pro should be works for this data flawlessly.
