Posted: Mon Feb 28, 2005 2:57 pm Post subject: Splitting camera download zip file to smaller specific files
The latest Safety Camera download has grown considerably in size with the addition of sound files, normal gatso files, speed grouped files etc... and now contains no fewer that 84 seperate elements. I know there have been several postings regarding confusion on which files should be used.
Full credit to Richard for compiling a comprehensive database.
However it would seem appropriate now to consider splitting the single download file into more manageable smaller zips that are perhaps platform specific or file type specific.
For example:
Splitting into a seperate 'safety camera zip' and 'speed grouped safety camera zip' or perhaps TomTom zip (.ov2), ALK zip (.xls) and even Navman zip (.csv)
This thread is to get people's views, the team's views and more importantly Oldie's views on this and whether such a move is beneficial and, of course, if manageable. _________________ Ian.

OK it's been a week, there have been over 100 views of this thread but zero replies.
There have been numerous requests for help regarding the files contained in the download, what they are for and which should be used. This has now prompted a thread here explaining all about them.
I was expecting some form of discussion, whether it be positive or negative, on the feasability of this and I am sure that Oldie would welcome your views as well. _________________ Ian.

It would make it far easier each time there was an update, if a file of 'new' or 'changed' locations was available, instead of starting each time with a database of 5000plus!
I have also asked for a regional database to be included but no discussion was offered. It would be covenient if I could exclude Ireland and Scotland until I wish to visit there. England could be split below N51, below N52, below N53 and above N53!
I realise that this database is a 'labour of love' and in no way is criticism implied, just discussion.

WHY ?
What's the problem, most people travel all over the country, why would we want to start having to load different regions, if you sync to the files what the problem, it's just done for you, and if like myself you use the zip file, then you just paste over the existing, so what's the problem, just don't get it!
To use the database for my Garmin iQue 3600 I have to:-
Use POI converter to Import .ov2 files
Convert them to .wpt
Save each file as Mapsource .mps
Import the .mps files into PalmDesktop
HotSync the cameras into the iQue.
These will duplicate the cameras from month previous so I must delete those!
Because the iQue cannot cope with the volume of locations [it slows up the re-draw] I have to setup the iQue specific programs 'wayQue' and 'Birdwatch' to handle the new database!
Can you find me an easier way please?
To have only to add 'new or changed' locations would help.
Richard Davies has introduced POI Grouper this week, and has made my selection of locations on my 'corridor' much simpler. There must have been some reason/need for him to introduce this.
quote-'What's the problem, most people travel all over the country'
I have travelled with a Caravan to Sorento, Rome, Venice, France, Germany, Austria in the last five years but have not been above the N52 point!
When I go to Scotland again I will load the maps and cameras into the iQue.
Oh well, it's nice to discuss it! Thank you.
How about it 'icsys'?

If you have special needs then I feel sure that you don't mind putting in the effort to meet them. You can use my POIManager program to determine which entries are new and which entries have been deleted. To find additions use the latest database file as the Update and the previous one as the Master. To find deletions use the latest database file as the Master and the previous one as the Update. Remember to uncheck the Append box for both uses.
I have very recently completed a program, POIGrouper, that will enable you to extract POI within a circular region.
Am I right in assuming that most people would prefer to have complete files rather than updates Updates would have to specify deletions as well as additions

One possibility is simply to run a 'diff' tool over a textual version of the old and new files. That will provide details of additions, deletions and changes, though care will have to be taken to figure out an appropriate sort for the database before diffing.

I use the POI-Sync service with POIEdit. I prefer complete files to replace the older one. Even when I manually unzipped the files and copied them to my PPC I preferred replacing the old files with the new ones.

I can see your problem, but if most or all of the files have new data then it must be more complicated to have edit the files before moving them to your unit.

Richard, since reading your post I have spoken to 4 other people who use the Safety Camera files, all including myself say they would only use complete files and would not use updates even if available.

It's good to see discussion has started although a file containing just 'new' or 'changed' locations is not quite what I had in mind.

Bearing in mind the above that suggests 'complete files' are what people want, I still feel that splitting the database into file type specific downloads such as ov2 (TomTom), xls (ALK), csv(AutoRoute) etc.. would perhaps be the most relevant.
If you adopted this method, you will still have the full-uk-gatso file and speed-grouped-gatso files in the same zip which are the basis of some confusion so it may be worthwhile to find some way of seperating them within each file type.
Perhaps another idea may be to place all the above into seperate folders thereby grouping each file type together within the zip
Alternatively you could have pocketgps_uk_full_sc.zip and pocketgps_uk_speedgrouped_sc.zip where you could download the first one if you just want all the camera locations or the other if you want to be told the speed limits of each camera as you don't need both!
Splitting like this means you only need to download the relevant files therefore cutting down the confusion.
Then theres the question of the sound files... TTG and Navman can't use wav files but TTN, and to some extent CoPilot, can.
As you can see, there is lots to think abut as there is no easy solution hence why I started this thread to discuss how it would be best to break down the database into a manageable download.
I think the first question to answer should be "Should the download be split?" if the answer is Yes then the discussion can continue until a suitable solution is reached. _________________ Ian.

Likewise, I prefer downloading the full archive and retaining them on the PC, but also update via POI Edits sync data feature.

I have Copilot v5 & TomTom, I also use Autoroute to pre-plan destinations for TomTom by saving the destinations Lat & Long and adding it to a favourites .ov2 file in TomTom then use navigate to POI. So would then need to download all 3 files.

This is always going to be a problem as new software and features are introduced, the original database was based around TomTom and additional programs written to use the .ov2, .bmp files, then came CheckPOInt and GPSAssist that allowed the use of .wav files to provide the warnings and ultimately to be able to use the speed related .ov2.
As navigational software is constantly being updated and new features being added, with more packages being able to use the database it's only going to grow. _________________ Graham.

A lot of work has been put into the FREE database, it doesn't hurt us to do our bit in sorting what parts we want, or has everything got to be put on a plate for us.

My suggestion for change (if change is really needed), would be to produce several different zip files, each with only the files needed for a particular type of GPS unit.
This would also allow the files to be pre-tweaked for various units (e.g. header lines removed from .csv files.
I am presuming that each of the file sets could be produced automatically from the master spreadsheet using macros/scripts, so would not take much admin effort, but would reduce the chance of confusion for new users.
On second thoughts, we would then have this forum full of messages from people who had downloaded the wrong version and could not make it fit with a hammer. _________________ Tomtom Go 1005

The size of the zip file isn't the issue and whilst there are some readme's for 'newbees' there are still new users who require help as can be seen here and here. Weren't you a newbie once too?

Someone who understands the logic behind my original suggestion...
