Hello, KartaView!

After 5 years of serving the mapping community through OpenStreetCam and over 7.6 million kilometers recorded by contributors all around the world, we’re now happy to announce a new product identity: KartaView.

As maintainers and developers of KartaView, it’s been an honor so we’re taking this opportunity to share more on what we’ve been up to recently and what contributors can expect in the near future.

But first… Why the new name?

In 2018, the OSM Foundation (OSMF) adopted a Trademark Policy discouraging names like OpenStreet-Thing. This was brought to our attention this year. In support of our good friends, we chose to embrace the name change.

Despite changing names a couple times (anyone remember OpenStreetView?) our mission has stayed consistent since the early beginning: we want to make OSM better by providing an open, collaborative repository of street imagery for the mapping community. So the imagery license, terms & conditions and privacy policy remain unchanged – we have no intention to be less open.

KartaView at Grab

As you probably know, in December 2019 the team and the project transitioned to Grab – the super-app of Southeast Asia and top contributor to OSM in the region. 

Since then, besides supporting the global mapping community we’ve been increasingly active in driving imagery collection in Southeast Asia. The region is still an under-mapped region of the world despite a population of over 650 million and we’re on a mission to improve that.

Earlier this year we partnered with local Grab drivers across 20 cities in Indonesia and Malaysia, recording a staggering 880,000 km of imagery in the span of a few months. All this data is publicly available on KartaView for everyone to use.

On the engineering side, we’ve been busy this year with significant infrastructure and pipeline improvements to support the growing platform, and while improving some things… others broke. Apologies to our active users.

Things are starting to look better and the engineering team is active on more future-proofing, which will be rolling-out in the coming months.

What to expect now?

First, kartaview.org will be the new home for the project. In the next few days, the other pieces like the mobile apps, JOSM plugin, Github repos will be updated as well. Some external projects integrating KartaView will probably need a bit more time to update the name, so most likely we’ll spot OpenStreetCam in tools and other corners of the internet for a while.

The name change will not break any existing integration (API end-point will be maintained) and changes to the legal terms and conditions are limited to reflecting the new name.

The Road Ahead

So now you know why we have to change our name and that our mission remains the same. There’s just so much around us that is unmapped, and we’ll always be at the forefront of this community-driven mission – to make OSM richer and better through imagery.

Thank you for being a part of the journey.

OpenStreetCam plug-in – Search Box for detection filtering

The most recent version of the OpenStreeCam plugin contains a new feature for improving detection filtering. This option became a need due to the significant growth of sign types. Its main purpose is to increase the ease of finding data. Therefore, the signs displayed in the characteristic area are reduced.

The team has added a search box to enable users to find a specific sign by entering keywords. To make filtering more relevant, the typed words should include the category, the sign name, or a combination of these two information. As a result, the detection type area will be sorted according to the input text.

This feature also works alongside the selected value for the region.

We’ll strive to continuously improve the OpenStreeCam plugin with new features!

OpenStreetCam and ImproveOSM are moving to Grab

Following Telenav’s strategic partnership with Grab, we’re announcing that the OpenStreetCam and ImproveOSM platforms are moving to Grab! The goal of contributing to the OSM project by supporting the community with tools and data remains unchanged, and users will continue to benefit from those platforms.

  • Data and applications: The data is available to the OSM community just as before, with better latency for many.
  • Open Source: Good news, the code license is changing from LGPL to the more permissive MIT license. The imagery license will remain the same, CC BY-SA version 4.
  • Policies: The Terms & Conditions and Privacy Policy were updated to reflect the project’s transition to Grab, other than that similar to the previous OpenStreetCam policies.
  • OpenStreetCam apps: The iOS and Android apps will now be published under the Grab AppStore / Google Play account – that makes no difference in contributing awesome imagery to the community! You can download and use the apps as usual.
  • Waylens: You can keep using your Waylens dashcams to contribute imagery to OpenStreetCam.

As always, we look forward to collaborating with the community members and improving OSM.

A fresh Cygnus+ version

Cygnus is a tool that helps the community improve the OSM map by comparing it with an external (local) map, and detecting differences between the two maps. The differences detected include road geometry and certain tags of interest (e.g.: ‘name’, ‘oneway’, ‘ref’, ‘maxspeed’) that are missing or have different value from OSM.

In this latest version of Cygnus, we have introduced new features and made a few overall improvements.

New Features

Minimum Way Length Distance

A new setting was added in this latest version: the minimum distance by which a way’s length in the OSM map may be extended using the external map.

Conflation setting which is defaulted to 15%. Maximum can be 50%

Extending a way’s length can be very useful where section of a road may be missing or a new road needs to be added. Existing ways will be extended when the local map has a significantly longer way (as defined by the maximum connect distance). If it is possible to connect the extended way to any new ways, this will be done automatically.

New Grouped Settings and Checkboxes

We have grouped settings for ease of use into conflation, way-related and tag-related groups.

New checkboxes were also created for adding/extending ways (to allow more refined usage), adding/changing tags and specifying a minimum lexical difference.

Conflation Results

The conflation zip file now contains a narration log detailing each change that is proposed by the conflation archive. The Cygnus+ output explains in the ‘telenav:action’ tag exactly what action was taken on each way (this same output goes into the narration log).

Improvements

The conflation algorithm was improved and also the readability of parameters on jobs in the queue.

We hope you benefit from those changes, and let us know if you have any questions or ideas for further improvements.

An ImproveOSM editor update

When we first released ImproveOSM, the Telenav initiative to share millions of potential missing road, turn restriction and one-way locations based on massive anonymized GPS signals from drivers, we also launched a custom editor based on iD.

The ImproveOSM editor, based on iD.

The editor provided an easy way to inspect ImproveOSM data and make OSM edits based on it.

Since then, we have worked hard to build out the functionality of the ImproveOSM JOSM plugin, and worked with the iD team to integrate ImproveOSM into the main OSM web editor.

These developments have made the custom editor obsolete, and we have decided to take it offline.

If you are interested in using ImproveOSM data to edit OpenStreetMap, please check out our JOSM plugin or select the ImproveOSM overlay in iD. You can also download the raw data from our ImproveOSM web site.

Thanks for using ImproveOSM and making OpenStreetMap better!

OpenStreetCam – Confidence level visualization

The OpenStreetCam plug-in has once again brought a new feature to help its users. It now allows displaying and filtering aggregated detections based on their confidence level. The confidence level represents a measure of confidence of the validity of the detection or aggregated detection.

New aggregated detections display

Aggregated detections can now be displayed using a confidence level based color code. This is an optional behavior that can be turned on in the plug-in preference settings by selecting the following preference:

If selected, each aggregated detection will be displayed with a border of the corresponding color, according to the legend table displayed under the check-box.

Map display based on confidence level:

If the checkbox is not selected, all aggregated detections are displayed with a white border.

Confidence level filtering

With the introduction of the confidence level attribute, a new form of filtering was added. Filter data now allows setting a value for minimum and/or maximum confidence level. When set, only the aggregated detections with the appropriate confidence level will be displayed.

The confidence level minimum and maximum must be values between 0 and 1.

ImproveOSM plugin – design updates

The latest version of the OpenStreetCam JOSM plugin has many design changes which make the usage more intuitive. The Telenav OSM team added new icons for the three main layers of the ImproveOSM plugin (Turn Restriction, Traffic Flow Direction, Missing Roads) and modified the cluster colors accordingly.

new icons in the menu

Also, some improvements were made regarding the visualization of turn restriction detections at a high zoom level. The color for the grouped detections was changed in order to match the aspect of the corresponding cluster and to facilitate spotting the detections from the map, the turn restriction icon was  changed too.

OpenStreetCam plug-in – Display OSMElement

A new feature has been added the OpenStreetCam plug-in that allows the visualization of the OSM Elements corresponding to the selected detection or cluster. OSM Elements are the basic components of OpenStreetMap’s conceptual data model of the physical world.

How to use the new feature

The first step is to select a detection or a cluster. If the selected item has OSM Elements, the Matched Data button from the details panel will be enabled.

Detection selected
Aggregated detection selected

By pressing the button, the corresponding OSM element will be drawn in the OpenStreetCam layer and it will persist until selection changes or the item is deselected.

There are three possible cases of display:

  • The element is of type Node:
Nodes are displayed using the JOSM node icon.
  • The element is of type Way:
Ways are displayed as a red line.
  • The element is of type Relation:
“From” element is displayed as a green line
“Via” element is displayed as a blue line
“To” element is displayed as a red line

Tags

Relations have a checkable option under preferences for tag display.

When this checkbox is selected, the tags associated with the OSM element members are displayed on the map.

Relation displayed with tags.

About OpenStreetCam

For those who don’t know OpenStreetCam, it is a free and open platform that uploads street-level imagery captured by your smartphone and detects salient features from the uploaded images such as signs, lanes and road curvature to improve OpenStreetMap. The images are collected by mappers for mappers and can be used in iD or JOSM to improve OpenStreetMap.

We have a ‘Getting Started’ guide on our blog!
