Question Web app that displays steep parts in red?

Hello

I use RideWithGPS to draw routes before sending them to my smartphone.

One thing that's missing, is showing the tough parts in red, where the roads are steep.

The only way to know if a route will have tough sections is to either move the mouse along the whole route, or use Google Maps with the Elevation option to check what the area looks like.

Is there an online web app that does this?

Thank you.

This web site ( routevisualizer) color codes the elevation on the route that you set up. When I last tried it was basically in beta development. Should work better now although I haven't used it since last year.

Not exactly what your looking for but in RWGPS the elevation profile is shown at the bottom, so you can see steep sections, zoom in in the profile (it automatically zooms the map to the same section) and move the cursor to the steepest point in the elevation profile to read out the grade.

Very cool. I just mapped a couple of my routes and ya, lots of short steep grades. Seems either going up or down the whole time and this gives me a easy to interpet visualization of my route. Thanks for the link!

The elevation profile also has an option to overlay a gradient graph, though it seems to overestimate rather frequently.

Cool, too bad it can only route where Google Maps is able to route, and everything above 16% is one color—there are big differences among 16–20%, 20–25%, 25–30% and 30+%!

While I can agree that it could be better at least it gets you a ballpark idea of what to expect on planning a ride in otherwise unknown territory. When you see those dark red/maroon areas you know you got something steep to deal with. The longer it extends the more B-busting it is going to be.

Basically the website tries to average out the sections. When you get to the steep areas ( >16°) the highlighted area might contain some really steep short sections. Those sections get averaged out by the software but at least you know the possibilities.

I've only used it on two of my routes but for the most part at least I knew when the big climbs were coming. Sometimes they will be easier than expected and sometimes harder but at least you have a heads-up and can prepare yourself for the worst ( depending on how long/steep they are ).

Yeah. Looking at recent ride there are a few elevation and gradient graph anomalies compared to reality. There's one particular steep short up and down that sticks out. Changing maps doesn't change the elevation or gradient, but when I look at the USGS topo map it shows a big knoll there and an old road going around it, apparently the way it was when the map was drawn but the end of the knoll has long since has been leveled with the road passing through the spot where the knoll was. RWGPS shows the hill that was there before but not there now.

Here's a screen shot from RWGS. The segmented red/white line shows the old road going around the knoll and the blue line shows the current road alignment cutting through it. It would be a very steep up/down if they hadn't put big cut there.

So...seems RWGPs elevation profiles are based on old USGS map data.

Veloviewer.com has some nice route visualizations.

Thanks for the links. I'll send a suggestion to RwGPS.

While I like the idea of a 3D visualization, just like with graphs you still have to mentally apply what is being displayed to what is actually being encountered when on the route. There in lies the problem. It's the scale that is the big problem. Hard to judge from these visualizations how long/steep the hill actually is, even when there is a distance reference. I just think most web displays are not going to accurately record the more steeper "short" climbs ( @ < 200' distance ). If you can expand the resolution perhaps that might change. RWGPS does this to an extent but still hard to visualize what is actual going to be encountered ( if you never ridden the route before )

Still, some information is better than no information. I'll use the information provided and tip my hat to the people who provided it.

This certainly shows WHAT YOU DID instead of WHAT YOU ARE PLANNING. Hindsight. With that note I don't have a suggestion that is closer to what you are asking for.

In velowviewer when you are looking at the graph you also see a map on the right. Again not good for planning a route you have never done.

MapMyRide USED to do exactly what the OP is asking for - show hills with bits in color depending on the grade. See example below. I really liked that and wish they'd bring it back.



This is my street - I have to ride up that daggum thing to go anywhere, and going home is uphill too. Go figure. (I live in the middle of it and it's one way on my side)

A really good app would also take into account the direction of movement. The same hill would anticipate red if going up and green if going down.

The routevisualizer website I mentioned before does that. It shows varying degrees of red for the climbs and various shades of blue for the descents.

With this subject in mind, wouldn't it be nice if you could edit routes on RWGPS to include prompts for when the big climbs were coming up. That would be sweet. ( Gee, are we that spoiled? The more we get the more we want. )

You could try gpsvisualizer.com, which does customizable elevation profiles from a variety of data sources including GPS recordings.

this is a real problem of the representation of data. I laid out a 225 mile route with some big hills. I was trying to avoid needless climbing, but some fairly large, nasty, steep hills got swamped in the data.
