Chart Converter Recruitment

[manimaul]

Interesting... it's been a while but Vadim posted a new kap to vrt utility script with border trim capability. Scroll down to the end of the page here:

#3175 (BSB driver to interpret PLY border polygon records at a header) – GDAL

You will find kap2vrt.2.py and the new bsb2gdal.py scripts by Vadim.

I haven't tried the new one yet...perhaps it might work better with BSB v2.

Nope, same issue... same easy fix though. I just copied the code for TRANSVERSE MERCATOR to UNIVERSAL TRANSVERSE MERCATOR and the utility works just fine for V2. I've got my lake working in Google Earth now so I can see my chart overlaid on the satellite imagery. It's also interesting to note where the charts are wrong! (showing lake where there is land, roads on different paths, etc.). A good argument for keeping the charts up to date! I'm going to try out the latest (Mar-2010) charts to see if there is any differences. Thanks for your help.

Greats manimal

this project may be of interest to you. see: MapTiler - Map Tile Cutter. Overlay Generator for Google Maps, Google Earth (KML SuperOverlay). Im sure your familiar with it already, based on this thread.

best of luck, interesting stuff.

Woops...that should have read "Greets Manimaul"....

I get error "expand incomplete or unrecognised"

any ideas

I earlier had a problem with compatability of converted .kap charts. They would work in OpenCPN and SeaClear but not in MaxSea and Fugawi. The solution was incredibly easy,just add a short code,f.ex. 'GE9999' in the # field of MapCal when you create the header file and,hey presto!! it works everywhere.

Through one of our programing vizzards here I now have a quick,easy and automatic way to convert Google Earth screens to calibrated .kap files without using MapCal. They are also fully compatible with Fugawi, MaxSea, OpenCPN and SeaClear.Very useful for the creation of calibrated harbour maps etc. The GE co-ordinates are collected by a small utility program via the 'ole/com' interface.

GREAT STUFF!!

(it's just a fancy GUI wrapped around gdal2tiles for folks who'd rather avoid working with command line apps)

That very useful...how will others find this method?

GE2KAP
This is a REXX program you need to install the oorexx interpreter.
Here are the instructions:

This program is written in REXX programming language and uses the oorexx interpreter. The lastest version of oorexx can be dowloaded from:

Open Object Rexx (please use V4.0.1 or higher)

You must have Google Earth V5.1 or higher.

This uses two programs other programs to create the KAP file:
1. Convert.exe from Imagemagick download at:
ImageMagick downloads:

install: ImageMagick-6.6.3-0-Q16-windows-dll.exe

and

2. tif2bsb.exe which can be downloaded at:
Browse libbsb - read/write/convert BSB images Files on SourceForge.net

and... this only runs on Windows (XP,Vista, Windows 7)

After installing all the prereqs, put this program, convert.exe and tif2bsb.exe
in the directory that the KAP file will be built and open GE2KAP.rex, then follow the instructions to create a KAP file.

A great and easy program to use for the creation of close-up calibrated harbour plans,and it works with all the popular nav progs. Created by Paul Higgins..

Map Tiler

Interesting program which accepts overlays of a variety of nautical bitmaps,including,strangely enough,.kap formats where the calibration data is read direct from the chart.

Needs a bit of experimenting to see the benefits but it is one way to overlay real navigation data,soundings etc. on a GE or GM background.

Works with all GE2KAP generated .kap files

Interlude Question: I'm trying to come up with a solid library of charts for world cruise, and wondering if I have the complete list of whats available for OpenCPN.

NOAA bsb,enc and cmap cm93s - is this the complete list? NOAA and CM93 2010? Or should we convert others? Is the "where to get charts" on the wiki up to date and complete?

[sinbad7]

REF MY #21 #24 #25

Here are a few samples using GE2KAP and Map Tiler.
Would have been great to be able to automatically save the overlaid results as .kap files.

The .kap files are readable by most popular nav. progs.

Hi there! Just came across this nice forum.

You may find this and a few related scripts here: Custom maps for maemo-mapper from BSB, OZI charts, and uncalibrated images - maemo.org - Talk
Some of them have "--help"

Hi all, I am new to this stuff but have been successful getting a rastor overlay on google earth. I tried setting up osgeo like manimaui shows but kept getting an Error 182 ordinal32 not found in proj.dll when i ran the command line using gdal2tiles....I can get the translate command to work and produce a .vrt then use Maptiler to produce the map...

I also would like to remove the borders from the charts and have downloaded the scripts from vadp but I am not sure where I should put them, folder etc. I keep getting a "kap2vrt.2.py is not recognized as an internal or external command operable program or batch file"

Sorry if the above questions sound stupid but I just started learing about all of this a 2 weeks ago and not being a formally trained computer programmer....well lets just say I would rather be sitting on the boat with a drink in hand!!!
