How to convert tiles to latitude and longitude in MODIS?
Many MODIS data products are organized in a tile grid based on a sinusoidal projection. You can find an online calculator here, that will convert from tiles to latitude and longitude coordinates. This tutorial will demonstrate how to perform this conversion in Python.
Where can I find the MODIS concentration level?
Accessed on 07/28/2015. All of the MODIS Chlorophyll-a Concentration Level 1 and Level 2 data can be found at http://oceancolor.gsfc.nasa.gov/cgi/browse.pl. All of the MODIS Chlorophyll-a Concentration Level 3 data can be found at http://oceancolor.gsfc.nasa.gov/cgi/l3.
Where do I Find my data in MODIS?
First you have to determine where your data is located within the tiled format MODIS data is distributed in. All tiles are denoted with a horizontal (h) and a vertical index (v). For the Land Products there are roughly ~350 or so tiles with varying degrees of actual land coverage.
How is the location of Harvard Yard calculated in MODIS?
All MODIS data are distributed in a custom sinusoidal projection, hence the rather weird looking shape of the map. In order to find the right tile we load a coordinate into R. In this case it’s the location of Harvard Yard, or 42.375028, -71.116493 latitude and longitude respectively.
How does the MODIS tile calculator work in Minecraft?
The MODIS Tile Calculator: determines the MODIS tile grid position, as well as the line and pixel within the tile, for any lat/lon point determines the lat/lon for a MODIS line, pixel within a tile specifies desired projection at the top of the page
How many resolutions are there in MODIS land?
MODIS Land. The MODIS Tile Calculator: The MODIS land products are produced at 4 resolutions (250m, 500m, 1km, and 0.05 degree), and in 3 projections (Sinusoidal, Lambert Azimuthal Equal-Area, and Geographic).
Where are the coordinates in MODIS land team?
The tile coordinate system starts at (0,0) (horizontal tile number, vertical tile number) in the upper left corner and proceeds right (horizontal) and downward (vertical). The tile in the bottom right corner is (35,17). Table of Tile Bounding Coordinates (10 deg tiles).
What are the geographic coordinates of MODIS land?
MODIS Land. The geographic coordinates of the upper-left corner of the upper-left pixel of a MODIS CMG image are -180.00 degrees longitude, 90.00 degrees latitude. The geographic coordinates of the lower-right corner of the lower right pixel are -180.00 degrees longitude, 90.00 degrees latitude.
How are pixel coordinates and tile coordinates related?
Pixel coordinates, which reference a specific pixel on the map at a specific zoom level. Tile coordinates, which reference a specific tile on the map at a specific zoom level. Whenever the API needs to translate a location in the world to a location on a map, it first translates latitude and longitude values into a world coordinate.
