Albin,

Sorry for not getting back sooner but I was out of town for a couple of days...
I dug up the CD's of BSB format charts I used when I sailed across the South Pacific in 1997/8. The files are in pairs i.e. 501.BSB (1KB) & 501_1.KAP (3,416KB) as well as REG2.BSB, REG2.IDX & REG2.KAP the contents of the 1st file is...

Hi Albin,

Sorry I didn't get back to you yesterday but we lost power for several hours yesterday and it shot a big hole in the day.

I have to think a bit about your suggestions on the coordinates issue, I am sure you are correct as ALL nautical charts come with a reference to it's scale and Lat/Long (on the top left corner and bottom right corner). They will probably be the answer but I will have to check first.

All the charts will have come from NOAA, British, or French, and dowenloaded to the local machine. ALL charts will be on a local HDD or on CD prior to a trip. There are several different formats still floating around as I noted in my last email. I know because I bought several to cover my South Pacific trip in 1997/8. BSB was the only format available and they came on CD at about $400 per CD. Now the US NOAA has them for FREE as a download in Raster or Vector formats.

I chose MS Access as its is small and movable and not really dependent on much to work. If I put an MS SQL DB behind it there would be lots of version issues (Windows versions that is). So the choice was made because of simplicity, size, and installtion perameters. I am open to MS SQL (been using it for 20 years) if it is installable on most versions of Windows.

As for your last suggestion I most certailny will look into Postgre's version "PostGIS"... I was totally unahware of the diffirent DB availabe for this type of project. WOW Back to the drawing board on this one!

Thanks

Hi Albin,

WOW! It is clear that you know your stuff around charting programs.

I am not sure where to start as some of what you have asked and offered I have no idea about.

First the Chart type...
•Raster Navigational Charts® (NOAA RNCs): bitmap electronic images of paper charts
•Electronic Navigational Charts® (NOAA ENCs): vector charts that conform to international standards
The BSB (raster) version is being phased out but still widely used all over the world. The Vector charts are more popular as they are a FREE download from NOAA.

I am not sure I know what you are asking when you asked for the coordinates? Is that the scalse of the chart? or the Lat & Long range of the chart? Both can vary depending on how much detail is needed. On an approach to an anchorage you would want the most detail on the other hand if you are crossing an ocean you want the inverse.

I have no problem using an already written product if I can interface with it and there is source code so if bug should be found I can address it. I do not want to re-invent the wheel if I don't have to! I looked at what was MapWinGIS which is now MapWindow and downloaded it yesterday and am still looking it over.

This as this will be used on boats at sea this is a WinForm application with an Access database behind it. There fore it needs no outside referances or sources once loaded. As I noted the charts can be downloaded prior top a trip FREE from NOAA. OR the user can purchase a set of BSB charts on CD.

Again thanks Albin. I hope this will give you more information about my project and it will help keep this dialog open so you can continue to suggest and guide me as know much more than I about the issues and products involved.

SquireDude 1-Mar-11 11:44am View

Sorry about not being explicit enough about the meaning of a map/chart my mistake. In nautical terms the word MAP is never used. A given area is called chart, not to be confused with an excell type chart! The electronic charts used in the marine/nautical world used to be the .BSB format and are now
•Raster Navigational Charts® (NOAA RNCs): bitmap electronic images of paper charts
•Electronic Navigational Charts® (NOAA ENCs): vector charts that conform to international standards
They are called RNC's (Raster Navigational Chart) and ENC's (Electronic Navigational Chart) using vector and raster graphics. Here is a link that better shows what I mean... http://www.nauticalcharts.noaa.gov/mcd/learn_diff_map_chart.html

I hope this helps clear up that point... my bad sorry.

To the next point you make... What functionality am I missing?
I am missing the functionality to display a nautical chart within my desktop (not web) application. I am not sure where to start. I have looked at several articles here that talk about mapping but mostly they are directed at displaying numeric values as colors or shapes (i.e. displaying a rough outline of the USA and coloring each state as to who has the most ground water reserves or potatoes.) My issue is very plain jane, display a given nautical chart for the area where you are currently (current lat/long position comes from a GPS interface). Then overlay a route with appropriate navigational waypoints along the way. Here is a NOAA on-line chart displayed and the type of functionality I need to include in my app. Again please note that my app has to be a stand-alone desktop app (WinForm) as it will be used by boaters at sea) http://www.charts.noaa.gov/OnLineViewer/18022.shtml

I hope this has helped and not hindered.

Thanks for your comments
Phill
