CartoType is a C++ library for rendering maps and finding routes that can plug into different data sources like OpenStreetMap. It uses a compact binary format called CTM1 to store map data efficiently. The library includes tools to convert OSM data into the CTM1 format. While routing is supported, turn restrictions are not fully implemented. CartoType is commercially licensed but the author is considering providing the compiled library to free and open source projects.

Euro30 2019 - Benchmarking tree approaches on street data
By examining the use of algorithms to solve the Prize Collecting Steiner Tree (PCST) problem we consider the facets which determine effectiveness. Specifically, by measuring a number of solution approaches and comparing them based on metrics. In order to understand the solution approach we must asses why it is useful. Our goal is to determine the effectiveness of Mixed Integer Programming (MIP) and heuristic methods. Utilizing freely available street and address data a base graph representation is created and then computed on. Such that a tree connects every address utilizing the minimum total length of edges from the street network. This is the basis of many approaches used to solve infrastructure problems including telecommunications network design and costing. The analysis is conducted on methods developed by Hegde et al. 2015, Ljubić et al. 2006, and Teitz et al. 1963. We present a data processing architecture, as well as a concise set of results and a framework for assessing the facets and trade-offs for a given approach. In this case the heuristic approaches are proven to have advantages in the simplistic case but fail when more complex requirements are added. This is where the MIP approach is able to capitalize, whilst detrimentally limiting the flexibility due to the strictness and specificity in modelling.

Postal Address Clean-Up - Two Unusual FME Workbench Applications
Helping a UK-based French 2017 election campaign using nationbuilder.com, the Liste Electorale Consulaire required four address columns to be normalised for upload. A previous FME WT presentation, to scrape web data and rank music playlists, inspired a similar usage against non-spatial data. Using three transformers, we got the first matches of address strings, assigned next address to empty address strings, and used country name as constant last string to built normalised string sets backward from it. A fourth transformer allowed to compare lists for QC and ongoing data uploads.
This talk will be presented by Richard Mosley of Safe Software on behalf of Andrew.

The document is intended to teach learners how to design effective maps using GIS software.
How Rough Is Your Runway?
Using Trimble TX9 terrestrial laser scanner my surveying team scanned an active runway in Western Australia to a tolerance spec of 3mm. The teams were working a live site providing aircraft right of way meant the teams had to setup and takedown scanner and targets to yield to any aircraft movements around the site and airspace. Surveyors took a ground based approach over drone UAS to maintain tighter vertical control than can be achieved using drone capture. We were tasked with looking for deviations, rutting and areas to derive Pavement Condition Index (PCI) criteria for their asset.
Once the data was captured surveying teams utilized TopoDot to assemble the raw scans into a consolidated model. They then attempted to use the pavement roughness algorithms in the software against the close to 3.4b points of classified data but had to split the datasets into halves and quads in order for the processing runs to complete. The Bentley product has an inbuilt “Road condition tool” which reports on pavement roughness characteristics but has preset expected pavement widths, roads not runway widths, set in the software. We explained to our surveyors that the algorithms might run faster in another product. It allowed us to explore FME as a point cloud processing workflow using feature tables functionality to quickly generate the statistics required for reporting deliverables using the entire dataset in one process.

Working with OpenStreetMap using Apache Spark and Geotrellis
The document discusses OpenStreetMap (OSM) and OSMesa, a framework for distributed processing of OSM data. It describes the OSM data model including nodes, ways, relations, and tags. It then discusses a use case where OSM change history needed to be processed at scale to backfill missing maps statistics. OSMesa was developed to handle this using Apache Spark and GeoTrellis on AWS. It can generate vector tiles, statistics, and other outputs from the full OSM history dataset in an efficient distributed manner. The future of OSMesa includes improved validation workflows, machine learning applications, and data science on OSM data.
Humanitarian OpenStreetMap Team [H.O.T.] Training for SBTF
OpenStreetMap is a collaborative project to create a free editable map of the world. It began in 2004 and now has over 1 million users who have collected over 1.8 billion geographic points and 170 million roads through GPS, aerial imagery, and other sources. The OpenStreetMap Foundation and Humanitarian OpenStreetMap Team support the growth of OSM for humanitarian and development contexts. Users can contribute geographic data by tracing imagery, surveying with GPS, or importing public domain data. The data is represented as nodes, ways, and relations which can be tagged and mapped on various online and mobile applications. Studies have found OSM data to be as accurate as commercial datasets where there is significant community mapping activity.

Implementation and Design of High Speed FPGA-based Content Addressable Memory
CAM stands for content addressable memory. It is a special type of computer memory used in very high speed searching application. A CAM is a memory that implements the high speed lookup-table function in a single clock cycle using dedicated comparison circuitry. It is also known as associative memory or associative array although the last term used for a programming data structure. Unlike standard computer memory (RAM) in which user supplies the memory address and the RAM returns the data word stored in that memory address, CAM is designed in such a way that user supplies data word and CAM searches its entire memory to see if that data word stored anywhere in it. If the data word is found, the CAM returns a list of one or more storage address where the word was found. This design coding, simulation, logic synthesis and implementation will be done using various EDA tools.
XML-athon with Don and Dean
XML is everywhere. It's used across the web, by devices, by sensors, and by many applications. It's also used to share data across organizations. We have a lot to thank XML for. However, it's complex nature can make it difficult to use.

In this special “marathon” webinar, learn about all things XML, and how FME makes it easy to access, leverage, transform and publish XML related datasets. In short, learn how FME enables you to get value from XML data faster than you imagined.
Robotics for Path Planning
This document discusses the application of robotics for path planning. It begins by defining robotics and describing some common applications of robots, such as jobs that are dirty, dull or dangerous. It then focuses on path planning, which allows robots to find optimal paths between two points using a map of the environment. Several path planning algorithms are described, including Dijkstra's algorithm, A*, D* and RRT. Map representations like occupancy grids and topological maps are also discussed.
Public Transportation Path Finder
The document describes acquiring, modeling, and exposing transit network data from Romania as semantic web data using RDF. It involves scraping route and stop information from websites, modeling the data using the Transit ontology, and storing it in a Virtuoso triplestore with SPARQL querying. The .NET API dotNetRDF is used to work with the RDF data. Key aspects covered include acquiring data from various agency websites, modeling the domain using existing vocabularies, technical details of the Virtuoso triplestore and dotNetRDF API.
Embedded Recipes 2018 - Shared memory / telemetry - Yves-Marie Morgan
To exchange data between processes without the overhead of locking/syscall, shared memory can be used. libshdata/telemetry offers a lock free circular buffer with timestamped data chunks to handle some typical uses cases found in drones:
One process for flying stack, and one a more processes for video computing.
Video processing can access drone attitude precisely with the frame
Logging of all the telemetry exchanged in shared memory is easily written in a file or to a remote ground station
Also work in AMP configurations
Build with live location data
