This Website is designed to help explore and plan trips to various caves in texas. The main structure of the functional components is such- A main html file, serving as an overview style Page. A page dedicated to our Query FUNCTION A page dedicated to our directions function. A sidebar button panel is consistent through these sites to allow seamless switching between functions. multiple html files were used for the sake of reducing code complexity while leaving room for additional functions to our existing sidebar.
This project presents an interactive web map visualizing population changes and demographic data in Hays County, Texas, from 2010 to 2020. The motivation for this project stemmed from the need to make spatial demographic data more accessible and understandable for local planners, researchers, and the general public. Population shifts, income levels, housing occupancy, and median age are critical indicators for policy-making, urban planning, and community development. A web map was selected as the appropriate tool due to its ability to combine geographic visualization with interactive querying, allowing users to explore complex datasets spatially.
This project's goal is threefold: identify and map problem areas within a 5-mile radius of downtown San Marcos, provide feasible, location-specific solution recommendations, and bring awareness to the lack of pedestrian-friendly infrastructure. The webpage provides an interactive map where viewers can select the highlighted roads and see where problem areas are. It also aim to include user and community feedback through a Google Form where users can inform us of locations they believe should be added to the map. Our hope is that our website can be used and accessed by a variety of people, and be used to spread awareness of the lack of pedestrian-friendly infrastructure in the city of San Marcos, Texas.
For our web map we created preset volcanic eruptions that are shown and can be selected through a drop down menu to show them individually or all at once with the show all option. The buffers are toggle-able when a preset is selected and can show or hide them. A custom buffer feature is also included that allows user input to click on the map and place a buffer of a size they type. A reset button is included to help git rid of the placed buffer and make the make go back to its default state. Zoom levels and features are added as well as a search function that allows users to type in an area and it will zoom into that spot, mainly to be used in conjunction with custom buffers or the moveable presets.
This web application is an interactive map that visualizes violent crime patterns across Texas between the years 2009 and 2019. The application displays a comparison map of crime rates in cities across Texas for the two selected years. Users can switch between 2009 and 2019 crime datasets, query cities based on crime rate and total crime, and create buffers around high crime areas. The application utilizes HTML, CSS, JavaScript, and ArcGIS JavaScript API 4.21. Feature layers and attribute tables are hosted on ArcGIS Online and accessed through the ArcGIS REST service. The crime information is derived from the Texas Department of Public Safety Open Data Hub.
This project was designed to make an interactive map of all the protected lands of Texas. By creating a buffer, a search tool, and a selection for your basemap; this interactive mapping creates a fun and informative site for viewers. As a group, we strived to make a simple hub for information on each park. When selecting each protected land, you will be greeted with a link to the appropriate website for booking and viewing of what the land has to offer. On the Navigation bar you can read the reasoning for the project as well as meet the creators of it.
