This is an overview of the current architecture of adding markers to a map. In particular, we are examining:

How images / icons are placed on the canvas.
How collision detection for touching icons work.
How an overlay for markers is structured.
How custom icons as an on device resource can be used (not getting the image from Mapbox servers).
Should we add OSM centric markers to the OSMOverlay or should we revamp ItemizedOverlay to draw markers from a QuadTree rather than a dumb list.

Note that this is using a recent revision of the mapbox android sdk.

Creating custom OBF files for OsmAnd

Setup

Make sure the latest version of java is installed.
Download OsmAndMapCreator from here: http://download.osmand.net/latest-night-build/OsmAndMapCreator-main.zip
Download a PBF file for your area of interest from Geofabrik (http://download.geofabrik.de/) or other source (e.g. activation wiki)
Create an OBF folder on your desktop
Unzip your OsmAndMapCreator folder to whatever location you want.

I've been interested in computer vision for a long time, but I haven't had any free time to make any progress until this holiday season. Over Christmas and the New Years I experimented with various methodologies in OpenCV to detect road signs and other objects of interest to OpenStreetMap. After some failed experiments with thresholding and feature detection, the excellent /r/computervision suggested using the dlib C++ module because it has more consistently-good documentation and the pre-built tools are faster.

After a day or two figuring out how to compile the examples, I finally made some progress:

Compiling dlib C++ on a Mac with Homebrew

Clone dlib from Github to your local machine:

PostgreSQL & PostGIS Cheatsheet

This is a collection of information on PostgreSQL and PostGIS for what I tend to use most often.

	blueprint:
	name: Frigate Notification (0.10.0)
	description: \|
	## Frigate Mobile App Notification

	This blueprint will send a notification to your device when a Frigate event for the selected camera is fired. The notification will initially include the thumbnail of the detection, but include an actionable notification allowing you to view the clip and snapshot.

	With this blueprint, you may send the notification to multiple devices by leaving "Device" blank and instead use a [notification group][1].

	# Beta-quality Landsat 8-oriented windowed pansharpener by Charlie Loyd

	# python3 panchunk.py $SCENE/*B{4,3,2,8}.TIF ${SCENE}-pansharp.tif

	# Then you may want something like this to brighten it up:
	# convert -channel B -gamma 0.96 -channel RGB -sigmoidal-contrast 40,14% ${SCENE}-pansharp.tif ${SCENE}-pretty.tif
	# But that will strip geo tags.
