Earth observation (EO) provides various multi-platform, multi-temporal, and multiresolution remote sensing imagery for dynamic monitoring of planet Earth, with a wide variety of uses. Crop monitoring is a typical application, which involves timely gathering of the information of crop types, boundaries, and dynamic changes during the whole crop growth period. However, most of the existing datasets and benchmarks focus on medium-resolution (≥ 10 m) classification of the main crop type by using satellite image time series (SITS), where the individual boundaries (parcels) and the dynamic changes of the crop cannot be obtained, due to the limited spatial resolution and the lack of multi-season annotation. In this paper, a multi-platform, multi-temporal, and multi-resolution (M3) remote sensing crop segmentation dataset (M3CropSeg) is introduced for very high resolution (VHR, 1 m) crop semantic segmentation to instance segmentation and dynamic segmentation. Specifically, M3CropSeg contains 16311 pairs of airborne VHR (1 m) and SITS (10 m) images, with 45 crop types and 101k instance annotations, covering a 26,000 km2 area of California in the U.S. M3CropSeg has various challenges, including M3 data fusion, class imbalance, fine-grained classification, and multilabel classification. Three tracks are designed for M3CropSeg, i.e., M3 semantic segmentation, M3 instance segmentation, and M3 dynamic segmentation, to obtain high-resolution pixel-level, parcel-level, and multi-season crop types, respectively. The corresponding benchmarks are also provided to address the above challenges, along with a variety of experimental analyses.

description: The MoDOT roadway coverage is based on a Dynamic Segmentation model. Dynamic Segmentation models linear features using routes and events, associating multiple sets of attributes to any portion of a linear feature. The ARC feature class forms the basic linear infrastructure from which Dynamic Segmentation models or route-systems are built. NODES indicate the endpoints and intersections of ARCS. The 'from-node' is the first vertex of the arc; the 'to-node' is the last vertex. Together, they define the direction of the arc. Arc-node topology defines connectivity of Dynamic Segmentation models or route-systems. Route systems are built without modifying the underlying arc-node topology. A route represents a single linear feature, such as a city street or highway. Routes are linear features composed of one or more arcs or parts of an arc; for example, a highway may be composed of a number of connected arcs. A route, for Dynamic Segmentation purposes, is simply a linear feature with measure values attached to it. Each route is associated with a measurement system, a linear method consisting of a starting value and other measures along the route, which describe distance along them. The measures are used to locate data that describe parts of the route. Data along routes is modeled using events. Event data, such as accidents, signs, functional classification, pavement condition, pavement type, is based on the Dynamic Segmentation model, the foundation of which is the route system. The state system network (IS, US, MO, RT) originated from 1980-DIME data, which was later updated with 1995 TIGER files from the US Census Bureau. Currently the coverage is updated monthly utilizing design plans, GPS, aerial imagery and county/city maps. All Census related fields have been removed, as they are not utilized nor updated by MoDOT.; abstract: The MoDOT roadway coverage is based on a Dynamic Segmentation model.

This coverage contains points representing tenth of miles in the GCMRC river mile system. The points fall along the centerline of the Colorado River from Glen Canyon Dam to the headwaters of Lake Mead. The points were generated from exported nodes from the "centerline" tenth mile route. The GCMRC river mileage was cross-checked with the traditional river guides and always fell within one mile of the guides, usually cooresponding within a half mile. River Mile 0 was measured from the USGS concrete gage and cablewa at Lees Ferry with negative river mile numbers used in Glen Canyon and positive river mile numbers downstream in Marble and Grand Canyons as per the Colorado River Compact of 1922.
This Route feature class is CDOT's representation of state highways. It can be used as the basis for dynamic segmentation, general reference, geoprocessing, and cartography.

We introduce a new methodology for analyzing serial data by quantile regression assuming that the underlying quantile function consists of constant segments. The procedure does not rely on any distributional assumption besides serial independence. It is based on a multiscale statistic, which allows to control the (finite sample) probability for selecting the correct number of segments S at a given error level, which serves as a tuning parameter. For a proper choice of this parameter, this probability tends exponentially fast to one, as sample size increases. We further show that the location and size of segments are estimated at minimax optimal rate (compared to a Gaussian setting) up to a log-factor. Thereby, our approach leads to (asymptotically) uniform confidence bands for the entire quantile regression function in a fully nonparametric setup. The procedure is efficiently implemented using dynamic programming techniques with double heap structures, and software is provided. Simulations and data examples from genetic sequencing and ion channel recordings confirm the robustness of the proposed procedure, which at the same time reliably detects changes in quantiles from arbitrary distributions with precise statistical guarantees. Supplementary materials for this article are available online.

General Description of Systemic Safety Analysis
The systemic safety approach “involves widely implemented improvements based on high-risk roadway features correlated with specific severe crash types. The approach provides a more comprehensive method for safety planning and implementation that supplements and complements traditional site analysis.” The systemic approach gives agencies another tool to address safety by allowing them to consider the risk of a site instead of its crash history. The general attributes of a systemic safety analysis include:
Identifying focus crash types and risk factors
Agencies need to identify a crash type to focus on, based on either statewide data or on an area identified in prior planning activities such as the State Strategic Highway Safety Plan (SHSP). Often the crashes associated with a focused crash types are randomly distributed across a network with few locations experiencing a cluster of crashes. For this analysis the focus was on bicyclist and pedestrian involved crashes.
Defining risk factors
After identifying a focus crash type, agencies associate those crashes with roadway or intersection characteristics. This association helps identify roadway characteristics that are correlated with a higher frequency or rate of that crash type. These characteristics, also known as risk factors, can be used to identify and prioritize similar locations where no crash history currently exists.
Screening and prioritizing the network
Risk factors (or roadway characteristics) are typically scored and weighted by agencies. This process of prioritizing characteristics allows agencies to take that information in combination and find areas within their roadway network that have higher concentrations of risk factors.
The resulting analysis identified roadways and intersections that have the greatest risk, regardless of existing crash history at those locations. Agencies can use this information to help select appropriate countermeasures and prioritize projects.
Data Used in this analysis
Crash Data
Ten years of crash data from 2009-2018 was used in this analysis. Only non-motorists crashes involving pedestrians, skaters, those using a personal conveyance, wheelchair occupants, bicyclists, and bicycle passengers were included in the analysis. Data as accessed July 8th, 2019.
Roadway data and Jurisdictional data
Roadway data was extracted from the Road Asset Management System (RAMS). The analysis included all paved roads within the state. Attributes included in the dynamic segmentation included number of lanes, average annual daily traffic (AADT), route name, shoulder width, shoulder type, shoulder rumble, speed limit, parking type, and median type. Jurisdictional data was also spatially joined to all the segments in the analysis including city, county, Regional Planning Agency (RPA), and Metropolitan Planning Organization (MPO). Roadways with minimum speed limits were eliminated from this analysis because pedestrian and bicyclist are prohibited from using facilities with minimum speed limits. The most recent access of this data was from September 20th, 2019.
Feature Class Description
The roadway segment data contained in this feature class includes all of the paved roadways within the state of Iowa. Each segment has been analyzed according to the general process described above and for this particular feature class the focus was on pedestrians. The primary output of this analysis was a composite score from 0-100 for each roadway segment. This score indicates the relative risk of the segment as it relates to the attributes used in this analysis. The lower the composite score the higher the risk. Higher composite score rankings suggest less risk at those sites. For rural pedestrian segments the minimum composite score was 24, the max was 100, and the average was 79.2. For the urban pedestrian score the minimum composite score was 17.5, the maximum 95, and the average was 60.3.

Dynamic panel regression results.
SDE_VDOT_RTE_OVERLAP_LRS - Used directly within RNS for dynamic segmentation and on local maps to show overlapping route name labels. Abstract: This feature class consists of approximately 492,000 features representing over 70,000 miles of Interstate, Primary, Secondary and Urban roads throughout the State of Virginia. The Linear Referencing System is based on the Virginia Department of Transportation's Source System of Record for road inventory, Roadway Inventory Management System (RIMS).Geometry and Attribution: The Linear Referencing System (LRS) data contained within this feature class provides dissolved route segmentation (i.e. routes are not segmented when they intersect other routes), thus rendering one table record per route. In cases where routes are noncontiguous (e.g. a valid physical gap exists), multi-part geometry is created. The feature class also depicts overlapping routes (e.g. Interstate 64 and Interstate 95) as two separate collinear features, one on top of the other. Routes built in the prime and non-prime directions are included. Each road centerline record has a master route record assigned. This feature class is best suited for labeling roadways when overlap reference is needed.Measures: The linear reference is based on Official State Mileage (OSM) as derived from reference points at Roadway Inventory Management System (RIMS) roadway intersections (i.e. nodes/junctions). Purpose: This linear referenced data layer represents roadways that are maintained by the Virginia Department of Transportation and provides the underlying spatially enabled geometric network to which all "events" (e.g. potholes, pavement type, vehicle accidents, traffic counts, culverts, etc...) can be located.
It represents a common national database for the sharing of geographical data considered a priority. The priority information contained is limited to the road system (all main roads and railways) present on the Regional Technical Paper at a scale of 1:10,000. It is a database with regional coverage created by the Interregional Center according to the data model and the Technical Specifications (N1005) of the State-Regions Agreement. Produced in shp format, starting from CTRN 10k data, it is limited to only "urgent information levels" relating to traffic and hydrography. Structural features are: - road conditions, graph structure with mixed standard between GDF-1 and GDF-2 and dynamic segmentation
One of the important challenges faced by humans in developing countries is the decline of soil conditions. The soil is so poor that it creates landslides easily and is a significant danger to the citizens of these countries. These landslide zones due to poor soil affect more than 300 million hectares of land. Furthermore, the citizens of these countries do not have enough resources to invest in soil restoration. (D Flanagan, 2002). The soil degradation is highly affected by rainfall which triggers the overland flow and soil erosion processes. (de Lima and Singh, 2002). Considering the above, we are proposing to develop an APP to identify zones that consider slope, protected forested areas, and proximity to bodies of water. Through these inputs we can decide which areas in developing countries should have additional forests . Adding Forests can mitigate the problems with the soil previously described and help comply with basic environmental standards. Forestation can be a cost effective solution for the countries that cannot afford to remove / improve the soil with machinery or retaining walls.
