kml

问题 I am building a large application using libkml. I am using the cmake port of libkml from here: https://github.com/rashadkm/libkml I am getting a stranged undefined reference to symbol error even thought the symbol appears to be referenced and defined. This is the make command: /usr/bin/c++ -fPIC -Werror=return-type -Werror=return-type -Wall -Werror=parentheses -Werror=uninitialized -Werror=missing-braces -fPIC -O0 -Wall -fPIC -fvisibility=hidden -fno-strict-aliasing -Wno-long-long -m64 -g -D

问题 I am using a kml file for displaying map with custom boundary lines. That kml file is downloaded from some website. In that file, inside the placemark tag there is no point tag for display icons. Eg: <Placemark> <name>Spot 2</name> <description>.....</description> <styleUrl>....</styleUrl> <MultiGeometry><Polygon><outerBoundaryIs><LinearRing><coordinates> ......... </coordinates></LinearRing></outerBoundaryIs></Polygon></MultiGeometry> </Placemark> That is what placemark tag contains in my

问题 I write an application that help people find appropriate places and show the direction to the target. Before, this functionality work well but now the draw route function does not work. The exception I got is that application can not download and then parse the kml corresponding to the route ( the code: xmlreader.parse(is); ), although the URL generated to get KML is correct (I test it in Browser) - for example: https://maps.google.com/maps?f=d&hl=en&saddr=21.04664,105.852203&daddr=21.040527

问题 I'm working on a project where I am utilizing tile overlays (visual) to display a rendering of the space, building names, accessibility, and parking spaces as well as KML polygons (functionality) to allow the user to click on various buildings or points of interest to bring up further information. My current issue lies in the organization of these various elements. At the moment, the KML polygons are appearing above all the tile overlays, including building names and parking which I would

问题 I'm loading a KML using KMLLayer in Google Maps API v3. Is it possible to reference the polygons on the map and do things like change color or transparency? 回答1: No you can't do it like that since there are no polygons like objects in a kmllayer. From the google docs: The Maps API converts the provided geographic XML data into a KML representation which is displayed on the map using a V3 tile overlay. This KML looks (and somewhat behaves) like familiar V3 overlay elements. KML and GeoRSS

问题 I have some legacy KML documents which includes a time stamp entry. Why is the below date not valid when using Instant to parse? Both methods are suppose to parse ISO 8601 formatted dates. String dateString = "2017-12-04T08:06:60Z" Using java.time.Instant.parse(dateString) throws an error "DateTimeParseException Text 2017-12-04T08:06:60Z could not be parsed at index 0." However, when using Date myDate = javax.xml.bind.DatatypeConverter.parseDateTime( dateString ) myDate is parsed correctly...

问题 I have a KML file and I extract the last coordinates and try to set them as a center of a Google Map but the marker is in a completely different place . Do I have to "convert" KML coordinates into google maps coordinates ? Thanks a lot 回答1: KML coordinates are x,y (longitude, latitude), whereas Maps uses LatLng (or y,x / latitude, longitude). Just switch the x and y order and you should be all set. 来源： https://stackoverflow.com/questions/9866925/coordinates-from-a-kml-file-not-displayed

问题 I am creating KML files from an ArcMap layer that uses XSLT to generate an HTML popup with custom links to file folders. Some of these links have embedded spaces. When I try to open these links in Google Earth, it does nothing. I have tried encoding spaces as %20 and still GE will not open them. It opens links without spaces just fine. Here is a link from my KML that works fine: <a target="_blank" href="file:///C:/Land/ce">Central Wildlife District</a> Here are a couple that don't: <a target=

问题 About 9 months ago, I created a set of classes in C# that correspond to KML 2.2 elements. So you can do things like myPlacemark = new Placemark("name"); Internally, it uses XmlDocument, XmlElement, etc. to create the various nodes and tags. It's a memory pig and it could probably be faster. No, I didn't generate the classes using XSD. I see there are posts on reading and parsing KML using Linq. However, has anyone used Linq to XML to create KML? If not, what do you think is the best approach
