Base map updating Talk live one to one phone sex cam no sign ups

It is estimated that existing government road databases are missing ~150,000 kilometers of resource roads and that more than half of the road mapping in the province is more than 7 years out of date.

Currently there is no one agency within government that is collecting and consolidating resource roads spatial components.

Plot Panel, -1, self.figure) = self.figure.add_axes([0,0,1,1],frameon=False) self.

Set Color( (255,255,255) ) #Basemap Setup = Basemap(llcrnrlon=-119, llcrnrlat=22, urcrnrlon=-64, urcrnrlat=49, projection='lcc', lat_1=33, lat_2=45, lon_0=-95, resolution='h', area_thresh=10000,ax=self.axes) drawcoastlines() drawcountries() drawstates() self.figure.canvas.draw() #Set up Scatter Plot m = Basemap(llcrnrlon=-119, llcrnrlat=22, urcrnrlon=-64, urcrnrlat=49, projection='lcc', lat_1=33, lat_2=45, lon_0=-95, resolution='h', area_thresh=10000,ax=self.axes) x,y=m(Long, Lat) #Scatter Plot (they plot the same thing) plot(x,y,'ro') scatter(x,y,90) self.figure.canvas.draw() # When plotting initially, save the handle plot_handle, = plot(x,y,'ro') ...

This question is similar but was not answered ( Currently I am closing the figure with clf(); however, this requires me to re-draw the entire basemap and scatter plot together.

On top of this, I am doing all of the redrawing inside of a wx panel.

The basemap redraw takes too long and am hoping that there is an easy way to simply re-plot scatter points only.

However, the data with this scatter plot changes based on user input.I would like to clear the data (only the data -- not the entire basemap figure) and re-plot new scatter points.
