Dear All,

I'm using Maxent but I have a problem when it begins. Some of my
points give the error :"[lat], [long], is outside the bounding box of
environmental data, skipping" .
This makes no sense since it only happens to certain points (near half
of it) that have not any formal difference from the ones which work.
I've read that some people has experienced the same error but to all
the points, but to me it only happens to some of them, reducing my
sample to near a half of the points.
As I said, all of the points are spelled in the same way in the csv
file.
Can you please help me??

best regards,
Luis

Hi Luis,

Are you sure that your enviro grids are in the same coordinate
reference system as your occurrence data? (or are you using SWD?) If
using ASCII grids, check the header of one of them in a text editor
and make sure that all your occurrences fall within the extent that
they cover.

If you use ArcMap, add an ASCII grid and your occurrence points and
clear the dataframe's coordinate system, then make sure the points are
within the grid.

check your resolution (cell size) and alignment also, that can lead to some bizarre-looking outputs.

I would also point out that NoData values within the maximum extents of your grid will also provide the above error.

Hi,,
you need to open of all of your ascii files that you use in your analysis and make sure that they all are having the same dimension (i.e. the same rows and the same columns). If you found that there are some files do not have the same rows & columns, you need to change that in all the files so that they will be all having the same number of Rows & Columns.

Hello, I am having this problem as well, I have projected all my
worldclim data in WGS 84 utm 35s. I have checked the rows and columns
of my ASCII files and they match. The only thing that puzzles me is
that when I open one of the ASCII files in arcmap and also my sample
points they do not match. But if I open them separately they are in
the right spot. Obviously my samples coordinates are in decimals. Can
someone please help, I am rather confused.

Should my environmental layers have the same number of rows and data?

How are you using them? SWD or ascii?

dear all,
i also have asimilar problem , my points keep falling out of boundary box and tried checking extent, co ordinatres, rows and columns and still not working.

Using a GIS software like ArcGIS or QGIS, please check the coordinate system of your rasters. They must match the coordinate system of your occurrence points. For example, if your occurrence points have lat/lon values (like those between +180 and -180), and your rasters havevalues that are really big (like 45000), that's a sign that your rasters are in a projected coordinate system, which means the coordinates are measured in meters, not degrees. There are many kinds of projected (meters, feet, etc.) and geographic (degrees) coordinates systems, and any difference can cause errors, so make sure they are the same for all your inputs. To change coordinate systems, project them to a different one with tools in the GIS software (google will tell you how). If this is not your problem, please specify further. Good luck!

Jamie
