The Colonization of Land

Changes in the environment of the early Earth drove the evolution of organisms. As prokaryotic organisms in the oceans began to photosynthesize, they produced oxygen. Eventually, oxygen saturated the oceans and entered the air, resulting in an increase in atmospheric oxygen concentration, known as the oxygen revolution approximately 2.3 billion years ago. Therefore, organisms that could use oxygen for cellular respiration had an advantage. More than 1.5 years ago, eukaryotic cells and...

Using Topographic Maps to Generate Topographic Profiles

Source: Laboratory of Alan Lester - University of Colorado Boulder Topographic maps are "plan-view" representations of Earth's three-dimensional surface. They are a standard type of map-view that provides an overhead, or aerial, perspective. Among the defining features of a topographic map are the contour lines that indicate locations of constant elevation. The elevation interval between the contour lines is dependent on the level of detail provided by the map and the kind of topography present.

Soft landing of mass-selected ions onto surfaces is a powerful approach for the highly-controlled preparation of novel materials. Coupled with analysis by in situ secondary ion mass spectrometry (SIMS) and infrared reflection absorption spectroscopy (IRRAS), soft landing provides unprecedented insights into the interactions of well-defined species with surfaces.

Equilibrium Rent: The Market for Land

The land is a critical factor of production that is supplied by landowners and rented by producers. For instance, farmers rent land to grow crops. Similarly, a restaurant owner may rent commercial building space to run the restaurant. The price for land is the rental price. Land can be bought, and in that case, the purchase price is the price paid to use that land indefinitely. However, in the current analysis, the rental price of land is used, as it presents a continuous payment similar to the...

Fate Mapping

2023
Fate mapping is a technique used to understand how embryonic cells divide, differentiate, and migrate during development. In classic fate mapping experiments, cells in different areas of an embryo are labeled with a chemical dye and then tracked to determine which tissues or structures they form. Technological improvements now allow for individual cells to be marked and traced throughout embryonic development and adulthood. This video reviews the concepts behind fate mapping, and then details a...

These methods provide complementary ways to determine position and elevation. Satellite positioning supplies location information, triangulation helps establish spatial relationships, and photogrammetry derives measurements from imagery. When combined with field surveying and sensor observations, they help produce maps and three-dimensional models that represent terrain and built features for engineering analysis.
GIS organizes, combines, and interprets location-based information from surveys, remote sensing, and other measurements. Spatial data processing converts these observations into usable maps and models, allowing engineers to examine terrain, boundaries, drainage, existing development, and other patterns together. This integrated view supports more informed design and planning decisions.
Three-dimensional models represent elevation and terrain form in a way that a flat map cannot fully show. They help engineers understand slopes, surface variation, and spatial relationships across a proposed site. By revealing physical conditions before construction, these models support site evaluation, infrastructure design, and planning for potential constraints.
Interpreting mapped terrain and features can identify slopes, drainage patterns, existing development, boundaries, and other characteristics within a defined area. These conditions may influence site selection, infrastructure layout, and construction planning. Examining them before a project is built allows engineering decisions to account for observable land conditions rather than relying on limited site impressions.
A workflow begins with field surveying, remote sensing, or other sensor measurements collected across the area of interest. Satellite positioning, triangulation, and photogrammetry can help establish location and elevation. The observations are then processed and organized through GIS to create maps or three-dimensional models for interpretation, design, and planning.
Engineering site mapping may combine field surveying with remote sensing, satellite positioning, triangulation, photogrammetry, GIS, and spatial data processing. Each contributes observations or measurements about location, elevation, terrain, boundaries, or visible features. Combining these sources produces a more useful representation of the site than treating any single observation in isolation.
Engineers use it during site selection, infrastructure design, construction planning, environmental assessment, and land management. The resulting maps and models provide information about slopes, drainage, existing development, boundaries, and terrain before work begins. This early spatial understanding improves decision-making and helps identify conditions that could affect the proposed project.
