Multivariate Analysis Web App

Sat, 21 May 2022 00:00:00 +0000

A basic web app to test a multivariate analysis with the files result of a post-processing analysis with satellite images. The application accept a (.pos) file to run the process.

Control Panel

The app shows a basic statistical description with the main values as box plots and histograms. In the processing threshold panel, we run a Mahalanobis algorithm to identify outliers in the data.

Outliers

Finally, in the adjusted data panel we get the results of statistics-adjusted data and their respective plots of the final output. The app allows downloading the output data in a (.csv) file.

Web App for Events Interpolation (Drone Images)

Wed, 09 Mar 2022 00:00:00 +0000

This web app allows you to interpolate events by uploading the corresponding “.mrk” and “.pos” files product of the post-processing kinematic (PPK).

The app currently accepts three different models of inputs (UAV). The main inputs correspond with the files .pos and .mrk and the corresponding Drone images.

Control Panel

The final product can be downloaded in a .txt format or .kml and it allows a quick quality check of the home point. The app also allows interaction with the final data in an interactive map and a table.

App Ubícame

Sat, 10 Jul 2021 00:00:00 +0000

Web app deployed using R shiny and a MySQL database to show the main customer data from different departments in Lima Perú. The relational database is composed of more than 100,000 customer addresses.

Control Panel

The app allows the suppliers to create clusters and filter data according to polygon data previously uploaded. The app also allows drawing a polygon by hand to filter data.

The app allows multiple formats of spatial data like: shapefile, json, mapingo files and KML. The administrators can upload new customer data using .txt files or typing data.

Web App for GTFS visualization

Sat, 10 Jul 2021 00:00:00 +0000

A pilot web app to read GTFS (.zip) files and show the spatial objects in a map with features like filters and search buttons to manage data efficiently. The application will also allow running some basic validations to identify missing required fields or files in the GTFS.

Base de datos

The app is connected to a relational database with the required datasets, the idea it’s to include the main fields and datasets of the reference page.

New features are coming soon. The idea is to have an application in which a user can upload a GTFS (.zip) file and run processes. New features will be implemented according to different needs.

Calculate travel times
Analyze route frequency and headways
Analyze calendar data
Create timetables for stops

Base de datos

The progress of the app is available at this Link. Currently, the app has a visualization interface with basic filter inputs.
