Hi all,<br><br>I tried very hard to understand where you are going unfortunately I cannot. Did I miss a location where the method, scripts are explained ? Do you need help ? Did the method accept (if it exist) ? What is the plan ? Who are the participants ?<br>
<br>I would like to help but at this stage how I can.<br><br>Michel<br><br><div class="gmail_quote">2008/12/7 Sam Vekemans <span dir="ltr"><<a href="mailto:acrosscanadatrails@gmail.com">acrosscanadatrails@gmail.com</a>></span><br>
<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">Thanks Steve for the breakdown :)<br>
<br>
I need to announce a couple points:<br>
1 Calgary sits smack in the middle of 4 tiles, and same with other<br>
cities, so that estimate 8, needs to be taken in as 4 of the '40'<br>
estimate.<br>
And winnipeg could be also like that too.<br>
<br>
2 (imo) when Dale started producing the tiles, he started with the 8<br>
or so 'popular' ones, (in our case, we can save these for later<br>
-last), and made a call out requesting people ask for particular tiles<br>
to work with.<br>
As people started working, calls came in announcing errors. So with<br>
some fixups (in the script) the next ones were better.<br>
<br>
3 the technical process of converting, seems to be an automated, but<br>
time intensive 1 person job, they will have the tiles and converted<br>
files all on their computer, they will also know what tiles have been<br>
loaded.<br>
4 how we all can help is in the manual messaging of the data, and<br>
reporting all 'bugs' in the script.<br>
<br>
By starting with the ones that users are prepared to take 'ownership'<br>
of the manual fixing, then once those tiles are 'imported & fixed' the<br>
rest should be clear sailing.<br>
<br>
I thing that sounds like a plan. Don't you?<br>
