For conversion of GPS to KML we used the GPS datatypes such asGPGGAwhich is described as Global Positioning System Fix Data andGPRMCwhichis described as Recommended minimum specific GPS/Transit data. To begin with, we first created two data frames with the given GPS data, by filtering out GPGGA and GPRMC types. As per our observation, we could see that GPGGAtype gave us information like Longitude, Latitude, Altitude, and Fix Quality (ifits 0 0 then it is invalid). On the other hand, GPRMC type fetched information like T Time, Speed in knots and Navigation receiver warning. Out of the other information from GPRMC datatype, we were only interested in speed and re-ceive warning. So we copied those columns and combined these columns into pandas data frame created for type GPGGA. Moving to the next part which is conversion of data. We converted the Latitude and Longitude of$GPGGA us-ing formula DDMMSSSS eg, 4533.35 is 45 degrees and 33.35 minutes. ”.35” of a minute is exactly 21 seconds. We checked for the direction and assigned proper sign as per the directon (W is -ve and E is +ve). We then converted all the numeric columns in dataframe for further calculation. Finally created a tuple with latitude, longitude and speed. This list of tuples was added as coordinates. One of the major challenge was to understand the GPS data.

Maps are currently experiencing a paradigm shift from static representations to dynamic platforms that capture, visualize and analyse new data, bringing different possibilities for exploration and research. The first objective of this paper is to present a map that illustrates, for the first time, the real flow of casual cyclists and bike messengers in the city of Madrid. The second objective is to describe the development and results of the Madrid Cycle Track initiative, an online platform launched with the aim of collecting cycling routes and other information from volunteers. In the framework of this initiative, different online maps are presented and their functionalities described. Finally, a supplemental video visualizes the cyclist flow over the course of a day.

The dataset contains plant species occurrence records in the upper to mid Tana River Basin, digitized from preserved specimens at the East African Herbarium (EA), Nairobi. The dataset is a subset of the EA BRAHMS database generated over several years through various projects and day-to-day digitization efforts. Specimen records from the Tana River Basin were extracted from the EA BRAHMS dataset then cleaned and formatted in Darwin Core Standard. Data cleaning was done using Open Refine Software as well as the GPS Visualizer tool to generate altitude values from coordinates. Elevation data from GPS Visualizer is controlled from a variety of reputable sources including SRTM, ASTER, USGS and Google Maps. Other cleaning tasks included correcting spellings, filling in missing data, checking the taxonomy, dates, and subnational administrative areas. Records without coordinates were georeferenced using GEOLocate, Google Maps, and Gazetteers. The field altitude (m) was automatically generated from GPS Visualizer (https://www.gpsvisualizer.com/elevation) to generate missing elevation values. The process involved uploading a CSV format file with latitude and longitude values to the website which then sampled these coordinates against inbuilt elevation profile files (Digital Elevation Models) to give altitude values at specified coordinates. Most coordinates were also retrieved from gazetteers as they are legacy data.

The construction of this data model was adapted from the Telvent Miner & Miner ArcFM MultiSpeak data model to provide interface functionality with Milsoft Utility Solutions WindMil engineering analysis program. Database adaptations, GPS data collection, and all subsequent GIS processes were performed by Southern Geospatial Services for the Town of Apex Electric Utilities Division in accordance to the agreement set forth in the document "Town of Apex Electric Utilities GIS/GPS Project Proposal" dated March 10, 2008. Southern Geospatial Services disclaims all warranties with respect to data contained herein. Questions regarding data quality and accuracy should be directed to persons knowledgeable with the forementioned agreement.The data in this GIS with creation dates between March of 2008 and April of 2024 were generated by Southern Geospatial Services, PLLC (SGS). The original inventory was performed under the above detailed agreement with the Town of Apex (TOA). Following the original inventory, SGS performed maintenance projects to incorporate infrastructure expansion and modification into the GIS via annual service agreements with TOA. These maintenances continued through April of 2024.At the request of TOA, TOA initiated in house maintenance of the GIS following delivery of the final SGS maintenance project in April of 2024. GIS data created or modified after April of 2024 are not the product of SGS.With respect to SGS generated GIS data that are point features:GPS data collected after January 1, 2013 were surveyed using mapping grade or survey grade GPS equipment with real time differential correction undertaken via the NC Geodetic Surveys Real Time Network (VRS). GPS data collected prior to January 1, 2013 were surveyed using mapping grade GPS equipment without the use of VRS, with differential correction performed via post processing.With respect to SGS generated GIS data that are line features:Line data in the GIS for overhead conductors were digitized as straight lines between surveyed poles. Line data in the GIS for underground conductors were digitized between surveyed at grade electric utility equipment. The configurations and positions of the underground conductors are based on TOA provided plans. The underground conductors are diagrammatic and cannot be relied upon for the determination of the actual physical locations of underground conductors in the field.The Service Locations feature class was created by Southern Geospatial Services (SGS) from a shapefile of customer service locations generated by dataVoice International (DV) as part of their agreement with the Town of Apex (TOA) regarding the development and implemention of an Outage Management System (OMS).Point features in this feature class represent service locations (consumers of TOA electric services) by uniquely identifying the features with the same unique identifier as generated for a given service location in the TOA Customer Information System (CIS). This is also the mechanism by which the features are tied to the OMS. Features are physically located in the GIS based on CIS address in comparison to address information found in Wake County GIS property data (parcel data). Features are tied to the GIS electric connectivity model by identifying the parent feature (Upline Element) as the transformer that feeds a given service location.SGS was provided a shapefile of 17992 features from DV. Error potentially exists in this DV generated data for the service location features in terms of their assigned physical location, phase, and parent element.Regarding the physical location of the features, SGS had no part in physically locating the 17992 features as provided by DV and cannot ascertain the accuracy of the locations of the features without undertaking an analysis designed to verify or correct for error if it exists. SGS constructed the feature class and loaded the shapefile objects into the feature class and thus the features exist in the DV derived location. SGS understands that DV situated the features based on the address as found in the CIS. No features were verified as to the accuracy of their physical location when the data were originally loaded. It is the assumption of SGS that the locations of the vast majority of the service location features as provided by DV are in fact correct.SGS understands that as a general rule that DV situated residential features (individually or grouped) in the center of a parcel. SGS understands that for areas where multiple features may exist in a given parcel (such as commercial properties and mobile home parks) that DV situated features as either grouped in the center of the parcel or situated over buildings, structures, or other features identifiable in air photos. It appears that some features are also grouped in roads or other non addressed locations, likely near areas where they should physically be located, but that these features were not located in a final manner and are either grouped or strung out in a row in the general area of where DV may have expected they should exist.Regarding the parent and phase of the features, the potential for error is due to the "first order approximation" protocol employed by DV for assigning the attributes. With the features located as detailed above, SGS understands that DV identified the transformer closest to the service location (straight line distance) as its parent. Phase was assigned to the service location feature based on the phase of the parent transformer. SGS expects that this protocol correctly assigned parent (and phase) to a significant portion of the features, however this protocol will also obviously incorretly assign parent in many instances.To accurately identify parent for all 17992 service locations would require a significant GIS and field based project. SGS is willing to undertake a project of this magnitude at the discretion of TOA. In the meantime, SGS is maintaining (editing and adding to) this feature class as part of the ongoing GIS maintenance agreement that is in place between TOA and SGS. In lieu of a project designed to quality assess and correct for the data provided by DV, SGS will verify the locations of the features at the request of TOA via comparison of the unique identifier for a service location to the CIS address and Wake County parcel data address as issues arise with the OMS if SGS is directed to focus on select areas for verification by TOA. Additionally, as SGS adds features to this feature class, if error related to the phase and parent of an adjacent feature is uncovered during a maintenance, it will be corrected for as part of that maintenance.With respect to the additon of features moving forward, TOA will provide SGS with an export of CIS records for each SGS maintenance, SGS will tie new accounts to a physical location based on address, SGS will create a feature for the CIS account record in this feature class at the center of a parcel for a residential address or at the center of a parcel or over the correct (or approximately correct) location as determined via air photos or via TOA plans for commercial or other relevant areas, SGS will identify the parent of the service location as the actual transformer that feeds the service location, and SGS will identify the phase of the service address as the phase of it's parent.Service locations with an ObjectID of 1 through 17992 were originally physically located and attributed by DV.Service locations with an ObjectID of 17993 or higher were originally physically located and attributed by SGS.DV originated data are provided the Creation User attribute of DV, however if SGS has edited or verified any aspect of the feature, this attribute will be changed to SGS and a comment related to the edits will be provided in the SGS Edits Comments data field. SGS originated features will be provided the Creation User attribute of SGS. Reference the SGS Edits Comments attribute field Metadata for further information.

This dataset is composed by a GPX file. It can be used to practice data visualization and more specifically GPS coordinates manipulation. Librairies like gpxpy or geopy (Nominatim API) can be practiced through this dataset.

Since the early 1990s, the GFZ has operated a global GNSS station network with currently about 70 stations for precise satellite clock & orbit determination, realization of the terrestrial reference frame, radio occultation measurements or studies on crust dynamics. A subset of these stations contributes also to the tracking networks of the International GNSS Service (IGS) and the EUREF Permanent GNSS Network (EPN). Other stations contribute to GFZ observatories (IPOC, DESERVE, TERENO), to the GPS Atmosphere Sounding Project (GASP), to WMO Global Climate Observing System Reference Upper-Air Network (GRUAN) or to other external cooperations. We offer data of 51 GFZ GNSS stations under this DOI. Nearly all stations are equipped with Javad or Septentrio hardware. Depending on the location and hardware they provide data of GPS (L1 / L2 / L5), GLONASS (L1 / L2 / L3), Galileo (E1 / E5a / E5b / E6), BeiDou (B1 / B2 / B3), QZSS (L1 / L2 / L5 / L6), NAVIC (L5), and SBAS (L1 / L5). The GNSS Station Nework Site (https://isdc.gfz-potsdam.de/gnss-station-network/) provides direct access to the 1s and 30s sampled RINEX data (near real-time, file based) and to real-time streams. Real-time streams are available for stations contributing to the IGS. Raw data GNSS binary raw observations are available upon request. All GFZ Stations follow the site guidelines of the International GNSS Service (https://kb.igs.org/hc/en-us/articles/202011433-Current-IGS-Site-Guidelines) Station specific metadata can be found at our metadata portal SEMISYS. An overview of the list of stations with direct links to the station specific metadata in semisys is available via ftp://datapub.gfz-potsdam.de/download/10.5880.GFZ.1.1.2020.001/2020-001_Ramatschi-et-al_List-of-GFZ-GNSS-Stations-with-links-to-SEMISYS.pdf.

NGO Kotkaklubi (Eagle Club) and 5D Vision Ltd have developed an online portal birdmap.5dvision.ee, to visualize GPS data of migratory birds. Current dataset serves as a copy of source data for this visualization. The portal operates since 2006. Birds of 12 different species have been monitored, total number of individuals has been more than 160. Currently over 850 thousand occurrences (GPS fixes) are stored in the database. The data is managed via web-based backend that enables different methods of importing gps data (Movebank, manual upload for different receiver data formats). As the dataset covers long period of monitoring different species, various types of GPS transmitters have been used. Illustrated data about species and individuals can also be added. To enable publishing of the data to GBIF, synchronization to PlutoF biological data management platform was developed. The aim of the Birdmap portal is to increase awareness, international communication about nature and its protection by combining the possibilities and advancements of modern technology with this attractive natural phenomenon as well as providing researches and decision-makers with visualized spatial data for using in environmental analysis of possible influence of large-scale infrastructure projects. (Due to legal reasons exact location data of species with highest protection category in Estonia, belonging to Estonian territory, are not disclosed in this dataset and are available on request.)

Uncorrected GPS/GNSS observational data collected using an Altus APS3G GNSS receiver on a 2m survey pole by Anne Hellie on the 19th and 20th of January, 2018 (UTC time).

The excel file “Uncorrected_data.xlsx” contains the output of eight different data files collected (SILLS to SILLS 7). The data has been compiled into the worksheet “Uncorrected_data”. The other worksheets contain copies of the notes from Carlson Surv PC (the software used to collect the points), along with a lot more metadata.

Using ArcGIS 10.3 and the XtoolsPro extension, “Uncorrected_data” has been made into an ArcGIS shapefile (*.shp) and GoogleEarth *.kml file. Both are named “4318_2018”, with their appropriate extensions.

Note that since these points were collected in autonomous mode (with no RTK or SBAS solutions), these are uncorrected data points, and have poor accuracy, particularly in the vertical (see the VSDV field for the vertical standard deviation).

The accuracy of these positions can be substantially improved by differentially correcting/post-processing the data. This can be done with the open source software RTKLIB. Using the Septentrio software (SBF converter), the raw data files (*.sbf files collected by the Septentrio unit) have been converted into Rinex *.obs files to facilitate this process. The base station files for the appropriate time period can be downloaded from the Geoscience Australia Geodesy ftp server. The closest base station (CORS) is located at Casey and known as “cas1”. ftp://ftp.ga.gov.au/geodesy-outgoing/gnss/data/highrate/2018/

The data is all about the occurrences of earthquakes in a geographical region (India and its surrounding regions). The metadata is :

• Sl. No.: Serial Number
• Year, Month, Day: Date of a particular earthquake as per UTC (Coordinated Universal Time)
• Origin Time of an earthquake in UTC and IST (Indian Standard Time) in $[Hour: Minute: seconds]$ format
• Magnitude of Earthquake: There are different ways to represent the magnitude of an earthquake. For your study, you can consider $M_w$, since we are deriving other types from $M_w$ only.
• GPS Location in terms of Latitude(Lat) and Longitude(Long) of an earthquake.
• Depth: Depth of occurrence of an earthquake in kilometer
• Location: Name of a region where an earthquake took place
• Source: The agency from which we have gathered the data, for e.g. IMD=Indian Meteorological Department, Min. of Earth Science, Government of India
  A sample row :

read as:
"A 3.3 magnitude earthquake occurred on 7th July 2016 at 22:24:02 (UTC). The location of the earthquake event was Jalpaiguri, West Bengal area with GPS location 26.8 N 89.5 E at a depth of 40km published by the source IMD"
