Has anyone had an issue with the points returned by the Google Directions API? The overview_polyline doesn't seem to match the directions I've asked for.
The Directions API gives the example:
http://maps.googleapis.com/maps/api/directions/json?origin=Toronto&destination=Montreal&sensor=false
In the JSON response I see includes:
"overview_polyline" : {

Decoding this using the Interactive Polyline Encoder Utility shows a path starting in Toronto as expected but going a different direction with an end point nowhere near Montreal.
Any ideas?
For background, I'm trying to use the polyline to generate a static map. The static map API allows passing encoded polylines.
I have had success using Mark McClure's tools:
http://facstaff.unca.edu/mcmcclur/GoogleMaps/EncodePolyline/
on archive.org
Your polyline works for me when I use this tool to decode it:
http://facstaff.unca.edu/mcmcclur/GoogleMaps/EncodePolyline/decode.html
on archive.org
and this to display the results:
http://facstaff.unca.edu/mcmcclur/GoogleMaps/EncodePolyline/encodeForm.html
on archive.org
Encoded polylines often have issues with "\" escaping the next character.
See this example [1] (can't seem to get it to display as a link)
with each '\' changed to a single '\'
From this issue where it does display as a link.

Hello I try to use api here map for findpickups, I tried to use the same example in the documentation Can you help me thank you

I want to make a QR Codes to automate a process for label printing using Easy Labels.
I've already created QR codes that contain file paths and part numbers.
Where I'm running into a brick wall is finding a way to include Control Commands, specifically Ctrl+o and Ctrl+p so Open File and Print commands are issued from the QR code.
I've searched for weeks trying to find a way and this community is the closest thing I've found to a glimmer of hope.
Since I'm trying to do this in plain text, I have no code, so I will provide the desired sequence when scanned by the operator.
(Ctrl+o)T:\Easy Labels\Customers\Toyota\MEX_mat.lab
(Ctrl+p)1704412
The goal is to make a fast and easy way for operators to print their labels as quickly as possible with as few steps as possible on their part with minimum errors.
When the QR is scanned, the first thing it will need to do is issue an Open File command followed by a string that contains the entire file path where the labels for that particular part is located in the database, then sends a return carriage to finish the open process.
Next, it will send a single space to clear a pop-up window message.
Finally, it will send a Print command followed by another string that contains the part number.
If I have to wrote code to accomplish this, assistance would be greatly appreciated.
The test QR code has been generated with Java code. It might or might not be helpful for you:
package qrcodetest;
import io.nayuki.qrcodegen.QrCode;
public class QrCodeWithCtrl {
public static void main(String[] args) {
QrCode qrCode = QrCode.encodeText("\u000fT:\\Easy Labels\\Customers\\Toyota\\MEX_mat.lab\n\u00101704412", QrCode.Ecc.MEDIUM);
System.out.println(qrCode.toSvgString(8));
}
}
In the code \u000f stand for CTRL+O, \u0010 stands for CTRL+P. The four digit number is in hexadecimal and goes from 0001 for CTRL+A to 001a for CTRL+Z.
The code uses the QR code library (available on Maven Central):
io.nayuki:qrcodegen:1.4.0
Thanks for any help you can provide! I've got a directions tool that lets users map a route to a start, finish, and 8 waypoints. I've also got a separate map webpage that loads about 2000 markers from a JSON object that uses latitudes and longitudes (no geocoding). I'm trying to combine these two into one mapping tool.
The problem is that when I run the combined map, I get an error in my console:
ReferenceError: QUERY_LIMIT is not defined
if(status == google.maps.DirectionsStatus.OVER-QUERY_LIMIT){
I checked out OVER_QUERY_LIMIT error with latitude-longitude addresses but it didn't seem to apply to my problem. Any ideas about what might be causing this error? Again, I appreciate your help!
Here's the line of code it's complaining about, with whitespace added for clarity:
if( status == google.maps.DirectionsStatus.OVER - QUERY_LIMIT ) {
Now you can probably see why that gets a QUERY_LIMIT is not defined message.
Can you find that code in your page? Should it have _ where it has -, so it would read OVER_QUERY_LIMIT?
Hi I've tried this a couple of ways and I'm not sure what I'm missing. The documentation here https://developers.google.com/maps/documentation/javascript/reference states that I should be able to set the center of my Map using the coordinates like this:
setCenter(latlng:LatLng)
which I am guessing means I can use the syntax:
myMap.setCenter(-37.8025182,144.9987055);
but I get the error "Uncaught Error: Invalid value for property : -37.8025182 "
Is there something I'm missing - the documentation doesn't really give me any clues.
Regards,
Lea.
The documentation says the single argument for setCenter is a LatLng. setCenter doesn't take two Numbers.
var centerpoint = new google.maps.LatLng(-37.8025182,144.9987055);
myMap.setCenter(centerpoint);
or combine everything together:
myMap.setCenter(new google.maps.LatLng(-37.8025182,144.9987055));
How can I find out the coordinates of an svg? I have an Adobe Illustrator file that contains a map, this has been drawn and separated into US states, how can I find the coordinates of each state?
I'm just using the US map as an example, I'm going to potentially use this technique for several other maps (much more local!!).
Inkscape does that beautifully. It has a command interface, described in http://tavmjong.free.fr/INKSCAPE/MANUAL/html/CommandLine.html . (The link is to a copy of the manual on the website of its author, Tavmjong Bah. Note that it warns that the manual hasn't been updated for the latest version of Inkscape. However, the command worked fine when I tried it.)
This command
inkscape -S some_file.svg
will output lines containing an element id, the x and y coordinates of the top-left corner, and the element's width and height. There is one line for each element of the SVG. Here's an example:
svg2293,26.447175,24,97.105652,92.450851
layer1,26.447175,24,97.105652,92.450851
MyStar,26.447175,24,97.105652,92.450851
This example comes from http://tavmjong.free.fr/INKSCAPE/MANUAL/html/CommandLine-Query.html . It extracts information from an SVG which includes a star shape, shown on my first link.
On my Windows 10 system, Inkscape lives in c:\Program Files\Inkscape\ , and the executables are in the bin\ subdirectory of that. If I cd to that subdirectory, Windows will recognise the inkscape command; likewise if I use the full path to the executable from somewhere else, e.g.
"c:\Program Files\Inkscape"\bin\inkscape -S some_file.svg
Putting it on my PATH would presumably also work.
Inkscape has a lot of other commands, which include others for extracting information about object positions and sizes. The latter are called "query commands". One can extract information about a specified object, e.g.
inkscape --query-id=zoom-in -X /usr/share/inkscape/icons/icons.svg
This is an example of finding the x position of the zoom-in icon in the default icon file on a Linux system.
To save the output to a file, use > . E.g.
"c:\Program Files\Inkscape"\bin\inkscape -S some_file.svg > coords.txt
As it's reassuring to see actual examples, here are two screenshots of this working.
Once you have the data in a file, you can read it into programs. Below is a screenshot of me doing this in the R programming language, using the read_csv function ( https://readr.tidyverse.org/reference/read_delim.html ). This puts the data into a table, which I then displayed.
SVG have an XML structure. The states will be in <path> tags, hopefully with the name of the state somewhere as an attribute. The coordinates of a path are defined by the d attribute, but they can get quite complex as they can be relative or absolute and have various types of curves. With curves, it's probably simplest to consider just the final two values, which is where the curve ends.
For full details, see: http://www.w3.org/TR/SVG/paths.html#PathDataGeneralInformation
The situation may be more complex if further transforms are applied to the paths. Good luck!
