Output from 'choice' in R's kml

由 Deadly 提交于 2019-12-08 09:48:28
问题 I'm having trouble getting 'choice' to create output. When the graphical interface launches, I am selecting a partition with the space bar. This creates a black circle around the partition, indicating it has been selected. When I click 'return', nothing happens. I checked my working directory to look for the output files, but they are not there. I used getwd() to ensure that I have the correct setwd(). No dice. There was a similar question posted: Exporting result from kml package in R;

Calculate nearest point of KML polygon for iPhone app

问题 I have a series of nature reserves that need to be plotted, as polygon overlays, on a map using the coordinates contained within KML data. I’ve found a tutorial on the Apple website for displaying KML overlays on map instances. The problem is that the reserves vary in size greatly - from a small pond right up to several hundred kilometers in size. As a result I can’t use the coordinates of the center point to find the nearest reserves. Instead I need to calculate the nearest point of the

问题 Using a KmlLayer object within the Google Maps API, is it possible to allow a user to adjust the transparency of the overlay.png features, referenced by some .kml file? 回答1: To the best of my knowledge it is not possible via standard google api but you can do this using jquery or some other library. KML images are just part of the DOM so if you can find the nodes you can manipulate their properties. Here is an example using jquery: <!DOCTYPE html> <html> <head> <meta name="viewport" content=

问题 I want to know if this is possible with google maps. I create a 2 small grids on google maps with kml file. How can I find out using php of if my address is listed in grid 1 or 2. Need help please. 回答1: I wrote code for doing exactly this, but rather than grids, for areas of the UK. I had to read the KML file like XML using DOMDocument::load() , this enables you to read the KML file and get the longitude and latitude points it contains. Bear in mind though that I had to change the KML

问题 We are trying to create a mapview with annotations loaded from a xml file. This works so far, and is making use of the KMLViewer code on the apple developer library. Now we are trying to load the data from the XML file into the detailview but only the corresponding entry. So when you click on details on a city for instance, details must be loaded from the xml file of that city. We are trying for days now but just don't know where to start. We have the following code now: detailviewcontroller

Referring to a Placemark in KML

由 南楼画角 提交于 2019-12-08 02:48:06
问题 Is there a way to refer to a placemark (probably by using the Placemark ID attribute) ? Use case: Suppose you have a list of bus stops in a city. Some stops will be common to many bus lines. If Placemark referencing was possible, there could be a master list of all stops and each line (set in a separate Folder) could just refer to one of the above Placemarks. Selecting more than one Folder would display the other Placemarks for those lines, but the Placemarks already displayed would not show
