How to change the resolution of a raster layer in R

由 扶醉桌前 提交于 2019-11-30 13:57:50
问题 I have several high resolution raster layers in R that I am working with. The level of detail is excessive for some of the analyses I am running, so I would like to speed things up by reducing the resolution. The coordinate system is UTM so the units are meters. The resolution says it is 30, 30 (x, y). So it seems that the resolution here is 30m. Could someone please advise me on how to change the resolution to 120m instead? I have read the help for the resample() and projectRaster()

Converting UTM (wsg84) coordinates to Latitude and Longitude

I've been searching for a while now (here and on google obviously) for a neat way to convert a set of UTM coordinates to Latitude and Longitude. I've got the coordinates and I know in what zone they are, but how do I convert this to Latitude and Longitude? I Was hoping there would be some kind of class that could do at least some of the magic for me, but it doesn't seem so :( Any suggestions on this? I know it can be done, as this converter seems to work just fine Geographic/UTM Coordinate Converter . Any input is greatly appreciated! :) Thanks! Take a look at this .NET library http://projnet

Open source PHP function for converting UTM coordinates to latitude and longitude?

由 送分小仙女□ 提交于 2019-11-27 16:34:57
问题 I'm making a PHP application involving Google Maps. Maps only accepts lat&lng pairs, and the data I want to display comes only with UTM style coordinates. Is there an open-source PHP function to convert from one to the other? Something like this would be great: $UTM_ZONE = '32'; $UTMX = '60329834,34'; $UTMY = '67382984,9'; $latlng = convert($UTM_ZONE, $UTMX, $UTMY); // $latlng = now looks like // array('lat' => '59.4472917501', 'lng' => '5.3928572425') 回答1: I've found sort of a dirty class

lat/lon to utm to lat/lon is extremely flawed, how come?

由 我的梦境 提交于 2019-11-27 05:51:16
问题 I've tried the following, input: lat/lon data then I'll calculate a box around it by, let's say 50 m, so +/- 50 m on easting/northing value. Now I reconvert it to lat/lon and with a script: http://robotics.ai.uiuc.edu/~hyoon24/LatLongUTMconversion.py I get a result that just can't be, lon before is around 7, afterwards around 2. zone, easting, northing = LLtoUTM(23, location.get_lat(), location.get_lon()) topUTM = northing + error bottomUTM = northing - error leftUTM = easting - error

Determining UTM zone (to convert) from longitude/latitude

I'm writing a program which expects a number of lat/long points, and I convert them internally to UTM in order to do some calculations in metres. The range of the lat/long points themselves is quite small -- about 200m x 200m. They can be relied on almost always to be within a single UTM zone (unless you get unlucky and are across the border of a zone). However, the zone that the lat/longs are in is unrestricted. One day the program might be run for people in Australia (and oh, how many zones does even a single state lie across, and how much pain has that caused me already...), and another day
