I am using mapdotnet services for our gis application to load the shapefiles, and this mapdotnet service wants the proj4 details. I'm getting them from spatialreference.org, but for this projection...

I am trying to create spinning globe with bars like in this example. You can see my example here. And everything goes fine until bars go over horizon. I have no idea how to cut bars from the bottom...

Based on the response and example made by Andrew Reid, I produced this pen code here points_in_subdivisons: on clicking on areas(Germany) on the screen We want to offer a smooth animation from o...

It's been a few years since Jason Davies blew us away with Reprojected Raster Tiles—that map stopped working because Mapbox is blocking his site, but the Mollweide Watercolour and Interrupted Goode...

Goal I'm attempting to build an application whereby the whole world map is split into a large number of hexagons. These hexagons, once generated would always cover the same area on the map. Then,...

I'm using this algorithm for Peirce world map projection in R. I'm able to do some fine maps, for instance using 28 as the value for the lambda_0 parameter in function toPeirceQuincuncial, since th...

I'd like to know the simplest way to plot vectors or oriented line segments on a healpy map, e.g. Fig 22 of this paper: https://arxiv.org/abs/1807.06212, screenshotted below. Is something like matp...

The question, in short: How can I accurately project a wrapping great circle radius in Mercator using something other than the Google Maps API? The question, in long: So I've got a conundrum. I r...

I work with satellite data organized on an irregular two-dimensional grid whose dimensions are scanline (along track dimension) and ground pixel (across track dimension). Latitude and longitude inf...

I'm currently stuck on achieving an equirectangular rotation on a 360° image with OpenCV because of my mathematical understanding (nearly zero) of projections and rotations matrixes. The result o...

I'm trying to define the right CRS for my sf object. I want to plot points atop the following layer (country: the Netherlands): Simple feature collection with 380 features and 3 fields geometry ty...

Lets say I request this image from the google static maps API https://maps.googleapis.com/maps/api/staticmap?center=52.591370,-2.110748&zoom=18&size=600x600&maptype=satellite&marke...

I created a custom SVG country map and plotted it with jVectorMap. Now I am trying to insert markers using lat/long on this map, but I don't understand how the "bbox" x;y system works. I guess I h...

I have the nice hexbin plot below, but I'm wondering if there is any way to get hexbin into an Aitoff projection? The salient code is: import numpy as np import math import matplotlib.pyplot as pl...

I am working on a world map that features a click to zoom feature. When clicking a country the map zooms in but the country is not always centered -- the same happens when you click out and repeat,...

I am trying to plot a polygon with geom_sf() in any projection other than lat-long. I am using the example found in the manual pages for geom_sf() Importing the dataset: nc <- sf::st_read(system...

I've been using using ggplot2 to plot climatic gridded data for years. These are usually projected NetCDF files. Cells are square in model coordinates, but depending on which projection the model u...

I try to use the raster reprojection of a map following this example. If I change the example kavrayskiy7 projection by the Azimuthal Equidistant projection, var projection = d3.geo.azimuthalEquid...

I'm trying to project a set of points ([long, lat] tuples) on top of an SVG map of my home country Austria: https://commons.wikimedia.org/wiki/File:Austria-geographic_map-blank.svg The descriptio...

I'm building a map of the Philippines with d3.js and for a strange reason the map looks like rotated on the left, so that the country doesn't look how it really is. I've tried to modify the projec...

I am using the CanvasTileProvider in Google Maps Android v2. I can convert lat long points to screen pixels. However I would like to create a method to convert a distance to screen pixels. This...

I am new to Hibernate and I am trying to get some data from the database. I don't want to get the full data but a projection of an entity. The thing is that in the for-loop when I get the id and t...

I want to plot some spatial data using the leaflet package in R, however the generated raster image seems to be shifted compared to a reference grid. I suspect map projection issue, but I am not ex...

I'm trying to create a pacific-centric Robinson projection in R with ggplot... converting a shapefile to a Robinson CRS using spTransform and setting longitude to 150 degrees doesn't work, and fo...
