Architectural and Engineering Documentation

The Historic American Buildings Survey (HABS), Historic American Engineering Record (HAER), and Historic American Landscapes Survey (HALS) programs offer representative samples of documentation archived in the Library of Congress. These samples serve as references for agencies, organizations, and individuals completing documentation in accordance with established guidelines.

Documentation Levels

These programs organize documentation into three levels, each with specific components:

Level I Documentation

Components include: - Outline-format report - Large-format photographs - Sheet set (with measured or interpretive drawings)

Level II Documentation

Components include: - Outline-format report - Large-format photographs - Reproductions of existing plans (if available)

Level III Documentation

Components include: - Short-format report - Large-format photographs

Sample Projects by Program

Historic American Buildings Survey (HABS)

Level I Documentation:
- Ellis Island, Contagious Disease Hospital Isolation Ward I (HABS NY-6086-Y)
- Cape Lookout Light Station, Lighthouse (HABS NC-203-A)
Level II Documentation:
- Mary Atherton Richards House (HABS HI-611-C)

Historic American Engineering Record (HAER)

All three documentation levels are available, though specific examples are not listed in the provided source.

Historic American Landscapes Survey (HALS)

All three documentation levels are available, though specific examples are not listed in the provided source.

Survey Series and Complexes

The collection also includes comprehensive documentation of larger projects: - Camp Greentop (HABS MD-611 series) - Free Library of Philadelphia (various HABS numbers) - U.S. Coast Guard Medium Endurance Cutter, 210' Reliance Class (various HAER numbers) - Northwestern Elevated Railroad (HAER IL-1197 series) - Cabin Creek Pumped Storage Hydroelectric Project (HAER CO-103 series) - Harold S. Gladwin Residence (HALS CA-129 series)

These documentation samples follow the Secretary of the Interior's Standards and Guidelines for Architectural and Engineering Documentation. While Federal mitigation documentation traditionally meets one of these defined levels, the HABS/HAER/HALS collection also accepts competition entries, student projects, and other donated materials that may not contain all elements of a specific level.

GIS and Topographic Data Sources

Free GIS data sources provide valuable resources for engineering professionals working with geographic information systems, environmental planning, and infrastructure design. These datasets cover various aspects including elevation models, weather patterns, and human geography.

Elevation and Topographic Data

Several sources offer free digital elevation models (DEMs) and topographic data:

EarthEnv-DEM90: A 90m-resolution near-global DEM created by merging the GDEM and SRTM products, with post-processing to fill voids and smooth data.
ETOPO1: A 1 arc-minute resolution relief model that includes ocean bathymetry.
Global Multi-Resolution Topography: Provides gridded elevation at approximately 100m resolution, covering both terrestrial and sea-floor topography.
MERIT DEM: A Multi-Error-Removed Improved-Terrain DEM created by removing multiple types of errors from existing DEMs including SRTM. Access requires emailing the developer for a password.
ALOS Global Digital Surface Model: A 30m-resolution Digital Surface Model from the ALOS satellite.
NASADEM: A 1-arc-second resolution DEM based on SRTM data.
EU-DEM: A 25m-resolution DEM covering the whole of Europe, available for download in tiles.
OpenTopography: A community-based site providing free access to high-resolution topography data, primarily clustered on the West Coast of the USA and in Greenland. Data is available both as dense point clouds and processed DEMs.
ArcticDEM: Provides detailed elevation models of all land areas greater than 60 degrees north, generated using photogrammetry from high-resolution satellite images.

Weather and Climate Data

WorldClim: Offers climate data for past, present, and predicted future conditions, including temperature (min, max, mean) and precipitation at a 1km x 1km resolution.

Water Resources

Water Productivity through Open Access of Remotely sensed data (WaPOR): Provides data to monitor and improve water and land productivity in agriculture, including evapotranspiration, interception, net primary productivity, and more.

Human Geography and General Data

Several sources offer data related to human geography and general environmental information:

UNEP GEOdata: A wide range of datasets from the United Nations Environment Programme, including Nighttime Lights, Pollutant Emissions, Commercial Shipping Activity, Protected Areas, and Administrative Boundaries.
World Bank Geodata: Various World Bank datasets converted to KML format, including GNP, schooling, and financial data.
Humanitarian Response Common and Fundamental Operational Datasets Registry: A list of freely available datasets for many countries run by the UN Humanitarian Response program, containing administrative boundaries, transport, population, and more.
Atlas of the Biosphere: Features gridded human data including per capita oil usage, literacy rate, population growth rate, built-up land, and many more.
Koordinates: A GIS data aggregation site including data in various categories such as administrative boundaries, transportation, etc. Some datasets are global, while others are continent or country-specific. Mostly vector data, but some raster data is available. Registration is required.

These GIS data sources provide valuable resources for engineering professionals working on projects requiring geographic information, environmental analysis, or infrastructure planning.

Dashboard Templates for Engineering Data Visualization

Effective data visualization is crucial for engineering professionals to analyze complex information and communicate findings clearly. Dashboard templates provide starting points for creating effective visual representations of engineering data.

Power BI Dashboard Templates

Power BI offers various dashboard templates that can be customized for engineering applications:

Marketing templates containing analysis for Google Ads, Facebook, LinkedIn, Amazon, HubSpot, and many other platforms.
Data stories available through the Power BI Data Stories Gallery, showcasing different types of dashboard designs.

Dashboard Design Principles

Effective dashboard design follows several key principles:

Start with a solid foundation and maintain consistency throughout the dashboard.
Focus on solving specific problems rather than creating visualizations for their own sake.
Tailor the dashboard to its intended purpose—for example, replacing an Excel report with a dashboard primarily consisting of a large table.
Consider the intended audience and their information needs when designing visualizations.

Wireframing Tools

Several tools can assist in dashboard design:

Mokkup.ai: A dashboard wireframing tool with a library of 150+ dashboard wireframe templates that can be customized according to requirements, with options to apply custom themes.

Community Resources

The Power BI community provides valuable resources for dashboard design:

Community Gallery: Features user-contributed dashboards and templates.
Data Stories Gallery: Showcases different types of dashboard designs and approaches to data visualization.

By leveraging these templates and design resources, engineering professionals can create effective visualizations of their data, facilitating better analysis and communication of complex information.
