that's in feature.js:

    if (Cartagen.zoom_level > 0.3) {

line 54

Could follow the format:

group_a: {
members: ['water','waterway','lake'],
fillStyle: 'blue'
}

As much as we can.

if we're at 90, 180, 270, 0, narrow the Viewport.

instead of the bbox.

It should also accept a single geohash (where we fudge the viewport)

or a geohash and a zoom level

it doesn't work anyways... or fix it, or reduce it

resolve the recent daily diffs errors (utf-8 related) first

haha this is a big one. Tiles@home just checks a giant png. Good luck.

test with /images/interstate.png

Consider the investment of queryign hash members vs generating neighbor hashes

Fade them in

add LabelOffset with labelOffset: 3 being 3px above the way

to stop initial beachballing

check for Config.resizable

(we'll have to make one of those)

resizing the canvas auto-clears the screen; let's not do this twice.

see revision in LOOM.

try woods-hole

Islands seem to cause some trouble.

Support IE 6+

in cartagen server

It was removed in r260 to make feature not disappear. The code needs to be
more robust and better tested.

Start at geohash length x, pretty short, say, 5 characters:

- if object count is below quota for this class of device, fetch lower tiles
    - also take into account power of client computer - base on screen size?
- this mitigates the density issue a bit

quota = n*device_power

base density on the heat map, see the osm-dev list. Or just do metropolitan areas for top 200
cities?

initialize: function() {
// Cartagen.observe('predraw', 'draw',this)

odd

Check if nodes which are members of ways may have tags. If so, aggregate those tags to parent
ways. Save independent nodes and display them with appropriate icon (this is dealt with in GSS) or
label. Check how many there are.

added meta tags but it didn't work...

Temap has used a library for dashed canvas lines. Perhaps we can add this to our Canvas class.

this should speed thing significantly

perhaps on a click event begins running in normal interactive mode. This would preserve resources
for initial load, and would be like clicking on a Flash movie to activate it.

use selenium to assure functionality of all GSS selectors and tags

lineWidth = 0 no longer works. You have to use: 0.00001

this has a fix originally in the Canvas class, but it seems to have broken again

Adjust UI and canvas size when a mobile device like the iPhone rotates.
Some old code from Events.js:

//if (Prototype.Browser.MobileSafari) {
// addEventListener("load", function() { setTimeout(updateLayout,
0) }, false)
// var currentWidth = 0;
// function updateLayout() {
// if (window.innerWidth != currentWidth) {
// currentWidth = window.innerWidth;
// var orient = currentWidth == 320 ? "profile" :
"landscape";
// document.body.setAttribute("orient", orient);
// setTimeout(function() {
// window.scrollTo(0, 1);
// }, 100);
// }
// }
// setInterval(updateLayout, 400);
//}

users should be able to specify styles on a zoom_level basis:

(http://code.google.com/p/cartagen/wiki/TagDictionarySpec)

way: {
zoom_level_1: {
fillStyle: "green",
fontColor: "red"
}
}

We seem to agree on the following:

way: {
zoom_levels: {
1: {
fillStyle: "green",
fontColor: "red"
},
2: {
}
}
}

http://trac.osgeo.org/proj4js/

add simplify parameter to GSS on a per-element basis

Live-loading only adds new ways, doesn't delete old ones with matching IDs... this is an argument
for a truly global ID, so we can make 'objects' a Hash and not an array... then we can knock old Ways
out by ID #.

separate this from Coastline code

we can request less if you're not rotated

Sometimes labels are rotated incorrectly.

Make Cartagen play nicely with pages when embedded, possibly allowing for
multiple maps in one page

Make sure Cartagen doesn't eat events meant for other page components

patterns are moving... can we center them, or fix their scale??? what's the deal?

also background/body pattern doesn't move when you pan.

Right now, it just breaks if you try to use the find controller to find a
location it can't geocode. We should have a more helpful error message, and
we should use AJAX to validate to location before the form is submitted.

TypeError: Result of expression 'way' [undefined] is not an object.

or just search the geohash it's in to see other labels and adjust (spring algorithm?)

create an Indicator class, right-align an array of notifications, show plots as 0/5, 4/5
