Query and order satellite images, aerial photographs, and cartographic products through the U.S. Geological Survey

I created a shapefile of Sundarban area Bangladesh. Here it is: Here is the projection information about it: I want this shapefile to project upon an image which is here [I downloaded it from earthexplorer USGS where the path and row is 138,45 respectively] while I was trying to project it using ERDAS software the shapefile does not appear. Here is the image: The image meta data is here: and the shapefile metadata is here: .

We will learn how to generate NDVI, NDWI, LST, and several other indices in just one click using a simple tool in QGIS. You only need Landsat imagery, such as Landsat 8, Landsat 7, Landsat 5, Landsat 4, or Landsat 3. Then, you simply need to install a tool from the plugin section of QGIS. After that, add your Landsat image and study area shapefile, and with just one click, you will be able to generate NDVI, NDWI, LST, and other outputs for your study area.

I have an SRTM file in DTED format obtained from EarthExplorer spanning 1 degree latitude by 1 degree longitude and containing 3601x3601 pixels at 30m spacing. The pixel size resolution is 0.000277777777778. This file is too large for my purposes, so I want to scale it down, but I have to keep the DTED format. I tried setting the resolution to 3 x 0.000277777777778 = 0.00083333333: gdalwarp -tr 0.00083333333 0.00083333333 input_file.dt2 downsampled.dt2 But this results in a 1200x1200 file, which is not a valid DTED size (I need 1201x1201), so I get this error: Creating output file that is 1200P x 1200L. Using internal nodata values (e.g. -32767) for image input_file.dt2. Copying nodata values from source input_file.dt2 to destination . Warning 1: The source does not appear to be a properly formatted cell. Warning 1: The corner coordinates of the source are not properly aligned on plain latitude/longitude boundaries. ERROR 5: Access window out of range in RasterIO(). Requested (0,0) of size 1201x1 on raster of 1200x1200. What do I need to change to get a valid output file? EDIT: after @user30184 's answer, I tried both of the following: gdal_translate -outsize 1201 1201 input_file.dt2 downsampled.dt2 gdalwarp -ts 1201 1201 input_file.dt2 downsampled.dt2 However, I still got the warning: The corner coordinates of the source are not properly aligned on plain latitude/longitude boundaries. The original file (3601x3601) covers latitude [29.9998611, 31.0001389] and has a pixel size of 0.00027777778. The downsampled file (1201x1201) covers latitude [29.9995833, 31.0004167] and has a pixel size of 3 x 0.00027777778 = 0.000833333333333. After further discussion with @user30184 , this is a valid result, as DTED files are supposed to expand outward from the boundaries by 1/2 a pixel size. Thus, both of the methods proposed in the answer are valid, and I can safely ignore the last warning.

In GIS and Remote Sensing, we can do many types of analysis using satellite images, such as Land Use, Land Surface Temperature, vegetation cover, flood risk, hazard mapping, Agricultural monitoring, environmental monitoring and many more. To do these kinds of work, we need satellite data. One of the best free sources of satellite images is Landsat, which we can download from the USGS Earth Explorer website. But before downloading any satellite image, we must first create an account on this website. In this video, I will show you how to create a USGS Earth Explorer account and how to download Landsat satellite images for your GIS and Remote Sensing work.
