GeoLib_v105 is now a library (as substack of the sample stack).

The new version has several additions. These are now the supported functions
(rightClick the hh-Logo in the sample stack to see the library stack script):

* getHaversineDistance(point1,point2)
* getDistance(point1,point2)
* intermediatePoint(point1,point2,fraction)
* greatCircleBearing(point1,point2)
* rhumbLineBearingBearing(point1,point2)
* getSpeed(point1,startSecs,point2,endSecs)
* isPointWithinRadius(centerPoint,radius,listOfPoints)
* orderByDistance(toPoint,fromList)
* getDistanceFromLine(point1,point2,fromList)
* getBoundsAndLoc(linesOfPoints)
* getPathLength(linesOfPoints)
* sexagesimalToDecimal(linesOfPoints)
* decimalToSexagesimal(linesOfPoints)
* getDestinationPointH(point1,distance,bearing)
* getDestinationPointV(point1,distance,bearing)

BerndN added a function to get one of 16 compass directions from a degree value.

Danke Hermann.

I am still planning to use something like this.

I have database with all dutch postcode with housenr's and longitudes 
and latitudes. This is now public information ordered some years ago by 
a Dutch Federal Judge as the post delivery appealed against this. But it 
is not easy to find the download, they hide it a bit.


Anyway i downloaded it as almost 1GB of csv data which turned into 
almost 8GB of database data. Took days to convert and upload it. It's 
around 6000 tables with also each around 6000 to 13000 entries.


Right now just used to find a place via postcode (LeitZahl) entry. And 
there some php examples on the web to calculate what you now have 
created, these calculations can be tricky.


(i know there are also online services for this with json data as reply, 
some for free until so many calls, but it's nice to be able to do it 
yourself)


Will check it out in time, and hopefully to be used when i expand my 
application.



Thanks a lot!

Jerry

BasicGeoLib_v100

2019-09-12 Thread hh via use-livecode 
Some specialists may be interested in the following, please report if you have 
any problem with the stack.

BasicGeoLib is a collection of very basic functions for using geoPoints.

The points have to be in the format: longitude,latitude in that order,
as decimal numbers, as in GeoJSON, NOT in Google.
That is the first item (longitude) is a decimal in range -180 to 180,
the second item (latitude) is a decimal in range -90 to 90.
And the third item is, if needed, a time in seconds (not an elevation
value).

Credits: Two core functions are based on the js-lib
## https://github.com/manuelbieh/geolib (MIT licensed)
and ported to LiveCode.

Supported functions (all in group "geoAction", rightClick an action
button to edit the script):

* getDistance(point1,point2)
* getSpeed(point1,startSecs,point2,endSecs)
* isPointWithinRadius(centerPoint,radius,listOfPoints)
* orderByDistance(toPoint,fromList)
* getDistanceFromLine(point1,point2,fromList)
* getBoundsAndLoc(linesOfPoints)
* getPathLength(linesOfPoints)
* sexagesimalToDecimal(linesOfPoints)
* decimalToSexagesimal(linesOfPoints)

I found no time to prepare the stack as library, please just copy the
functions you need or make your own library.
