markers

I have a Leaflet map with a layer called flickrpics that is loaded dynamically in geojson based on the bbox of the current map view. I would like to get a simple count of the number of markers in that layer, so that I can display it next to the layer label in the layer control. I've tried things like flickrpics.length but it's saying undefined. Apologies, pretty new to Leaflet and javascript! Reference: https://leafletjs.com/reference-1.3.4.html#geojson Methods inherited from LayerGroup: getLayers() Layer[] Returns an array of all the layers added to the group. var pins = L.geoJson

I need icons (PNG) and polygons on my map. So I create icons as markers and polygons as polygons. Unfortunately regardless of creation order polygons are displayed "below" markers. I need is vice-versa. Is there a way, how to do it? ghybs EDIT: Correct default panes order in Leaflet 0.x: (from top-most to bottom-most) objectsPane popupPane markerPane <= all markers icon (other than L.CircleMarker ) shadowPane <= all markers icon shadow overlayPane <= all vectors (including L.CircleMarker ) tilePane So just using the marker's icon shadow is not enough. You have to manually change the z-index of

I'm trying to draw on a map using markers. The problem I'm having is when I try to add lots of them, then I can't get it to run. To illustrate my problem, let's say I want to draw a square made of 900 smaller squares (30x30). By the way, I do need those squares, not just one big square I'm trying to add the markers to an itemizedoverlay, then drawing it. the code is below. Any suggestion how I could do that? Thank you very much!! public class MainActivity extends MapActivity { MapView mapView; MapController mc; GeoPoint p; static Context context; int k=1; List<Overlay> mapOverlays;

I have a data set with 9 columns. 7 features are used for feature selection and one of them for the classification. I used tsne library for feature selection in order to see how much my data could be classified.The result from tsne is shown in picture. However, I want to visualize my data in another way. I would like to set a color for each observation based on the column f1 (id). for example : f1(id) f2 f3 ... f9(class label) 1 66 77 ... A 1 44 88 ... A 2 33 55 ... B 2 77 88 .. B colors come from f1 and shapes come from f9 . I do not know how to do it! I would appreciate for your comments or

i am having trouble with custom quick-fixes, which i want to provide in my Eclipse plug-in, and i'm hoping for someone more experienced than me in Eclipse PDE to have some hints for me on this issue. As i have understood, i can provide custom so-called "quick fixes" (or "resolutions", in Eclipse inside terminology), by extending the extension point org.eclipse.ui.ide.markerResolution for a specific marker id, such as for example some default Eclipse marker, org.eclipse.core.resources.problemmarker . This works for me for the default marker types and for custom marker types, BUT : The

I am trying to put a scatter plot together from multiple data files, to see how the correlate to each other. The code looks like this: hold all fia = fopen('data.txt'); A = fscanf(fia, '%f %f %f', [3 inf]); t = A(1,:); a = A(2,:); r = A(3,:); figure(1) scatter(log(r),log(a),'r', '-'); fclose(fia); fia = fopen('data.txt'); A = fscanf(fia, '%f %f %f', [3 inf]); t = A(1,:); a = A(2,:); r = A(3,:); figure(2); scatter(log(r),log(a), 'g', '-'); fclose(fia); And so on, where the next data points are plotted on the same graph: fia = fopen('data.txt'); A = fscanf(fia, '%f %f %f', [3 inf]); t = A(1,:);

I am using ARToolkitPlusBenchmark to scan AR Tag Marker . I can easily detect all 4096 BCH marker .But my problem is i can't getting idea how to detect each BCH marker id ? I have found code from here ARToolkitPlusBenchmark I have tried to detect marker in Markerinfo.java class DetectMarkerWorker extends Thread { private byte[] curFrame; public DetectMarkerWorker() { setPriority(MAX_PRIORITY); start(); } @Override public synchronized void run() { try { wait(); } catch (InterruptedException e) { } while (true) { if(!CurrentConfig.ONLY_CAMERA_PREVIEW){ long tick = System.currentTimeMillis(); if
