I have a database of locations by lat/long. Trying to overlay on a background image that is a map using the **Lambert conformal conic projection**. I have the following specs on the map
_Map\_Projection:_
_Map\_Projection\_Name:_ Lambert Conformal Conic
_Lambert\_Conformal\_Conic:_
_Standard\_Parallel:_ 45
_Standard\_Parallel:_ 33
_Longitude\_of\_Central\_Meridian:_ -100
_Latitude\_of\_Projection\_Origin:_ 38
_False\_Easting:_ 0.000000
_False\_Northing:_ 0.000000
_Planar\_Coordinate\_Information:_
_Planar\_Coordinate\_Encoding\_Method:_ Row and column
_Coordinate\_Representation:_
_Abscissa\_Resolution:_ 262.47750
_Ordinate\_Resolution:_ 262.46550
_Planar\_Distance\_Units:_ Meters
Does anyone have the code for correctly mapping the coordinates on the background?

Hi @CAVUCO
Maybe this helps?
It’s from the Processing’s giCentre Utils library
[https://github.com/gicentre/gicentreutils/blob/main/giCentreUtils/src/org/gicentre/utils/spatial/LambertConformalConic.java](https://github.com/gicentre/gicentreutils/blob/main/giCentreUtils/src/org/gicentre/utils/spatial/LambertConformalConic.java)

package org.gicentre.utils.spatial;
import processing.core.PVector;
First two lines in this code above. I found the resource but there is no way to download it. I guess I just don’t know how to navigate around.

No, these imports are standard imports from the library itself. Don’t worry about them.
You have to install the library giCentre first with the tools in the IDE.
You’ll find examples there, but not of the Lambert conformal conic projection.
The lib, however, has such a Class, That’s the link above. You can find and use the methods to use for the projection there. Or even better, see the reference in the library folder at “Processing/libraries/gicentreUtils/reference/index.html”.

The [gicentre site](https://www.gicentre.net/software#/utils/) has also a Processing library called geoMap, only downloadable there.
